Manchester United are in the process of handing out new deals to up and coming youngsters, and have rewarded three midfielders with new contracts after young goalkeeper Joel Pereira committed his future to the club.

United U21 midfielder Matty Willock has expressed his delight after extending his deal with the club following his move from Arsenal in 2012.

"Happy to have extended my contract," Willock wrote on his official Instagram account, while United are still to confirm the deal at their end.

The young midfielder moved from the Gunners in the summer of 2012, progressed through the youth ranks, and is now touted to be a regular member in Warren Joyce's U21 squad.

Willock has two brothers Chris and Joe, who are still with the Arsenal academy, but the former made his first-team debut during the north London club's summer pre-season tour of Singapore during the Barclays Asia Trophy.

The Red Devils have also reportedly handed out new deals to midfield duo Timothy Fosu-Mensah and Josh Harrop, who have been impressive for the reserve team last season, according to the Express.

The former has agreed his first professional deal with the club after joining from Dutch side Ajax at the start of last season. The Dutchman, who can either operate in the midfield or as a centre-back joined United for a fee in the region of £300,000.

Harrop, on the other hand, has also reportedly been handed a new two-year deal after coming through the ranks and establishing a place in Warren Joyce's U21 side, according to the Daily Mail.

The midfielder, who travelled with Louis van Gaal's team for their pre-season tour of the United States, could be sent out on loan in order to get more regular first-team experience.
