Erik ten Hag is set to bring his Ajax No2 Mitchell van der Gaag with him to Manchester United.

Ten Hag has agreed a deal in principal to join the Red Devils next season after he received a formal offer from the club on Tuesday.

He still has to negotiate the terms of his departure from his current role and make a decision over the backroom staff he will take to United.

The Daily Mail says former centre back Van der Gaag was promoted to assistant manager by Ten Hag at the start of the season, after having the No 1 job at eight teams including Maritimo of Portugal and Ajax's reserve side.

The 50-year-old is known for forging miserly defences, including at Ajax, who have conceded only 15 goals in their 29 league matches this season while scoring 85 at the other end.

Former United and Arsenal striker Robin van Persie is also being lined up for a return to Old Trafford.

The 38-year-old is now a coach at his old club Feyenoord, his first backroom role.

There are concerns over whether the former striker would give up that job, as he is also coaching the club's youth sides, including his son.
