Man United kid Hannibal is growing in stature, Andrey Santos already looks the part for Chelsea while Liverpool's Ben Doak is set for first-team chances... who's impressed so far in pre-season from the Premier League's chasing pack?

• e-mail

The Premier League season looms large now and teams only have around three weeks to bring themselves up to speed. 

We've seen a proactive approach to the transfer window, with lots of the top sides getting business done early as they've jetted off on their respective pre-season tours. 

But incomings aren't the only things fans should be getting excited over, with a plethora of promising young talents ready to burst onto the first-team scene. 

From the likes of Chelsea's midfield stars Cesare Casadei and Andrey Santos to Newcastle's Elliot Anderson and Harrison Ashby, there's plenty to get excited about. 

Will any of them be able to make the step up and help their teams in the race for Premier League glory? Here, Mail Sport takes a look at the youngsters that just might.

Arsenal

Amario Cozier-Duberry, 18

Cozier-Durerry is yet to play this pre-season but has been handpicked to travel to the USA with the senior squad.

After only signing a professional contract last summer, his progression has impressed the likes of Jack Wilshere, who said the winger reminds him of Bukayo Saka. 

Seen as one of the brightest sparks in the Gunners' Hale End academy, he has fought his way up after joining at the relatively late age of 14 and was part of the team that got to the FA Youth Final last season.

Ethan Nwaneri, 16

Nwaneri is a precocious attacking midfielder who, last September, had the honour of becoming the youngest english top flight footballer of all time at 15 years and five months. 

He is not part of Arsenal's travelling party across the pond but did come on in their draw with Nurnberg and made an impression, cracking a shot over the bar. 

Arsenal recently announced him as one of their first-year scholars for 2023/24, so his future is in north London for now.

Chelsea

Cesare Casadei, 20

Casadei was one of Chelsea's standout performers in their 5-0 win over Wrexham, controllling the midfield tempo and making aggressive runs forward with the ball.

His debut won plaudits from fans. Casadei joined from Inter Milan last summer, scoring five goals in 13 Premier League 2 outings before spending some time on loan at Reading, getting 15 appearances under his belt.

Lewis Hall, 18

Hall made his mark in the 2022/23 season with 11 first-team appearances and won Chelsea's Academy Player of the Year award. 

The left-back is highly rated but only featured in the second half against Wrexham and didn't have much to do. 

Andrey Santos, 19

Santos made his Chelsea debut in their victory over Wrexham and he already looks the part. 

The teenage midfielder was strong at ball retention, spraying passes on the turn, and made solid defensive contributions including a slide to block a shot. 

Having signed from Brazilian side Vasco de Gama, it might take him some time to bed in, but Chelsea have been left so deprived of options in the midfield that the £18m man could have his chance soon.

Liverpool

Conor Bradley, 20

Bradley began Liverpool's dramatic 4-2 victory against Karlsruher in right-back, with Trent Alexander-Arnold further ahead in midfield. 

The 20-year-old has the fitness that Jurgen Klopp demands of his players. He ran out 53 times for Bolton Wanderers during his loan there last season and bagged an impressive seven goals. There, he won the club's Player of the Season award and was a key part in the winning the EFL Trophy. 

He is also versatile, able to slot into the right side of a defence or midfield.   

Conor Bradley featured 53 times for Bolton last season and was their Player of the Season 

Bobby Clark, 18

Clark started in Liverpool's win over Karlsruher and is building a reputation as a composed No 8.

The Newcastle-born youngster came through the academy system of the Magpies and would put in extra hours beyond training to improve his skils.

After the game, Klopp said he did 'really well' in the first half and he could be in line for more game time this seaoon after cropping up in 2022/23.

Ben Doak, 17

Doak was introduced in the second half against Karlsruher and instantly went about imposing himself on the game. His run on the break 60 minutes in drew the first yellow card of the match as the German side scrambled to stop him.

The winger, signed last summer from Celtic for £600,000, could benefit from Liverpool's involvement in the Europa League this campaign. He already has five competitive games under his belt for the reds. 

In the UEFA Youth League, he ran out eight times and regsistered four goals and four assists.

Manchester United  

Amad Diallo, 21

Diallo has been a fixture in Manchester United's pre-season starting in their wins over Leeds United and Lyon

United are weighing up what to do with the winger and could yet send him out on loan to Leicester or Leeds. 

The 21-year-old has proven that he can find the goal. Last season, he scored 14 goals in 42 games on loan at Sunderland and will hope this year can be his year, having initially turned out for the Red Devils in 2020/21.

Kobbie Mainoo, 18

Mainoo has also been in the starting 11 for both of the Red Devils' pre-season fixtures and caught the eye with positive performances, shining at the base of the midfield. 

United fans went crazy when he was seen breezing past Fred in training. He made his senior debut earlier this seaosn and racked up three appearances. 

The Stockport-born midfielder won the club's Young Player of the Season award for 2022/23.

Hannibal Mejbri, 20

Hannibal is another youngster to have played both games so far. In the first, he was a strong influence but should have buried a gilt-edged chance minutes in. 

The creative youngster has been a bright spark and is no stranger to United fans, having played in previous seasons. A loan at Birmingham City last year won him lots of admirers.

One of those admirers just so happens to be Borussia Dortmund - they've been interested in signing him as a long-term replacement to Jude Bellingham but Erik ten Hag wants to see him over the course of the pre-season.

Newcastle 

Elliot Anderson, 20

Anderson bagged a goal in Newcastle's 3-2 over Gateshead and an assist in their 2-1 win over Rangers. He is set for a big year on Tyneside. 

With six starts and 21 appearances from the bench last season, the Scotland U21 international is already integrated into the squad. 

According to our north east football reporter Craig Hope, 'Anderson’s versatility will be key for Newcastle in what is likely to be a 50-game-plus campaign.'

Elliot Anderson broke into the Newcastle first team last season and is a versatile midfielder

Harrison Ashby, 21

What better way to endear yourself to your new fanbase than with an 88th-minute winner?

That was the story for defender Ashby against Rangers, with his headed goal sealing a 2-1 win at Allan McGregor's testimonial.

Over three seasons at West Ham, he made seven appearances, and while it will be a fight to gain minutes at St James' Park, he won the praises of Mark Noble during his London spell.

Lewis Miley, 17

Miley only signed his first professional contract back in May but has forced a way into Newcastle's pre-season, appearing from the bench twice.

Having joined the Magpies' academy at the age of seven, he is somebody who has dedicated lots to the club to even be at this stage.  

A substitute debut against Chelsea on the last day of last season was reward for his hard work as the midfielder became the club's youngest-ever debutant.

Spurs 

Alfie Devine, 18

Devine got some football under his belt when he came on as a substitute in Spurs' 3-2 loss against West Ham.

Deployed in an unfamiliar winger position, he made the best of his circumstances and his shot, which was saved, led to Spurs' first goal. 

The England U20 international will be hoping for more action after two outings in the last three seasons. Could Ange Postecoglou be the man to put faith in him?

Pape Matar Sarr, 20

Sarr's future at Tottenham is up in the air, with multiple Ligue 1 sides seeking him on loan, despite the fact he only joined from Metz last summer. He came on against West Ham. 

Last season saw him in a Spurs kit on 14 occasions and the Senegal international anchored the midfield well in the Champions League against AC Milan. 

He is in Spurs' squad for their Asia-Pacific tour and will hope to make an impression. Fans have spotted his potential in the past.

Destiny Udogie, 20

Udogie was on the scoresheet against the Hammers.

Spurs bought him from Udinese last summer but was immediately loaned back to the Italians, where he has now put together two seasons of consistent football. 

With defensive upheaval occurring under Ange Postecoglou, the wing-back could have an opportunity to step in and take opportunities this campaign.
