Erik ten Hag calls up four Under-21 stars to first-team training at Manchester United

Manchester United boss Erik ten Hag has welcomed four of the club's Under-21 stars into training with the senior side.
The Red Devils are preparing to host Nottingham Forest on Saturday - live on talkSPORT.
United have had a mixed start to the season, with their 1-0 win over Wolves being followed by a 2-0 defeat to Tottenham.
A home match against Forest this weekend gives them the chance to return to winning ways, and Ten Hag could turn to the club's youngsters for help.
Steven Railston of the Manchester Evening News reports that four youngsters have been involved in first-team training on Wednesday.
Hannibal Mejbri, Isak Hansen-Aaroen, Omari Forson and Marc Jurado missed the 1-1 EFL Trophy draw against Stockport on Tuesday night.
This is due to their involvement in training with the senior side as they prepare for Saturday's fixture at Old Trafford.
Midfielder Hannibal, who has been capped on 24 occasions for Tunisia's national team, is the only one out of the four to have played for United's first team, making three appearances so far.
The 20-year-old is also reported to have started in a behind-closed-doors match against Burnley, in which United lost 3-0.
Hansen-Aaroen, Forson and Jurado, all 19, are yet to feature at senior level, although the latter has been an unused substitute.
All four players compete in Premier League 2 for United, with the club finishing 9th in the 14-team league last season.
An appearance against Forest could be a possibility with Ten Hag already a man down ahead of the clash.
It was announced on Tuesday that Mason Mount will be out of action until the international break due to injury.
The 24-year-old will therefore be unavailable for selection this weekend and their crucial upcoming match against Arsenal.
