Inter's most expensive signings - How the Nerazzurri spent almost €1.8 billion on incoming transfers

After coming through the ranks at Atalanta, Bastoni made his debut in November 2016 and Inter came calling in the summer of 2017 after just three appearances for the Bergamo side, paying a hefty €31 million for the centre-back before loaning him back to Atalanta for two seasons.

However, they recalled him back in 2018, renewed his contract until 2023 and then sent him to Parma for another loan spell.

The defender has since returned to Inter and is currently a key part of Inter's starting XI in both Serie A and the Champions League.

Inter pounced on the opportunity to lure Barella away from Cagliari in 2019, initially signing him on a one-season loan with an obligation to buy.

Barella made 27 appearances for Inter during the 2019-20 season and Inter spent €32.5m to land him on a permanent basis, with a four-year contract taking effect.

The Italian star then led Inter to Scudetto success in 2020-21, was selected as the best midfielder in Serie A and earned a place in the league's Team of the Year as well.

In 2021, Barella signed a contract extension with the club until 2026.

After eye-catching performances for Sampdoria in the 2016-17 season, including becoming the youngest defender to make at least 35 appearances in Serie A, Skriniar moved to Inter in the summer of 2017 for €34m.

He signed a five-year contract and became the most-expensive Slovak player of all time.

With over 150 appearances for the Nerazzurri under his belt already, Skriniar is rapidly on his way to becoming a legend at Inter.

Part of the excellent Monaco team consisting of players like Fabinho, Berbatov, Bernardo Silva, Anthony Martial and many more, Kondogbia helped lead the Ligue 1 side into the Champions League after almost a decade-long absence in 2014-15.

In their dream run to the quarter-final of the tournament, Kondogbia also scored a goal against Arsenal in the round of 16 and in the summer of 2015 Inter came calling, splashing €36m on the Frenchman, who signed a five-year deal.

Kondogbia spent three seasons at Inter before moving to Valencia and later Atletico Madrid.

Nainggolan moved to Roma from Cagliari on a six-month loan in January 2014, before permanently signing for them in the summer of 2015 for €15m.

His performances for Roma saw him become one of the most sought-after midfielders in Europe, with some of the top English clubs vying for his signature.

But Inter won the race for the Belgium international's signature, signing him in a deal worth €38m in the summer of 2018 (€24m plus Davide Santon and Nicolo Zaniolo).

However, the Belgian only featured for one season at Inter as he was loaned back to Cagliari until the summer of 2021.

In August 2021, Inter announced that they had terminated Nainggolan's contract by mutual consent and four days later he signed with Belgian club Antwerp.

Crespo arrived at Lazio from Parma for a then world record-breaking fee of €56.81m in the summer of 2000.

After incredible performances across two seasons at Lazio, featuring alongside superstars like Jaap Stam and Gaizka Mendieta, Inter came kncocking on Lazio's door and agreed to pay a fee of €40m for the Argentine in 2002.

However, Crespo spent just one season at Inter before being sold to Chelsea for €26m.

The striker returned to Inter in 2009 and later to Parma in 2010, where he retired.

Inter won the race to sign the much sought-after Joao Mario in the summer of 2016 from Sporting CP for €41m, making him the second-most expensive signing in their history at that time.

However, he grew increasingly frustrated with limited playing time under then manager Luciano Spalletti, before securing loan moves to West Ham in 2018, Lokomotiv Moscow in 2019 and Sporting in 2020.

In the summer of 2021, Mario moved to Benfica on a five-year deal.

After a one-season stint with Real Madrid's senior team followed by two seasons on loan at Borussia Dortmund, Hakimi moved to Inter in the summer of 2020.

Inter had to pay €43m for the Moroccan, who was in high demand at that time.

Hakimi, however, only lasted one season at Inter before Paris Saint-Germain decided to pay a fee of €60m for the defender in the summer of 2021.

Inter broke the transfer record in 1999 to sign Christian Vieri for €46.48m, making him the most-expensive footballer in the world at that time.

The Italian striker was part of a dream attacking partnership with Brazil great Ronaldo, but because both players were injury prone, they didn't play together often.

Vieri was impressive in his first two seasons, but later, due to too many managerial changes, he couldn't make much of an impact.

After scoring his 100th goal for the club 2004, he left for Milan on a free transfer in 2005.

In 2019, Inter splashed out €80m to lure Lukaku away from Manchester United.

The forward spent two seasons with Inter, winning the 2020-21 Serie A title and being named the MVP of the campaign.

His performances at Inter were so good that he was even nominated for the Ballon d'Or in 2021.

After two seasons at the Serie A giants, Lukaku returned to his former club Chelsea in the summer of 2021 for €113m.

After struggling to establish himself in the Premier League, however, he was loaned back to Inter in the summer window of 2022 for one season.
