Nicky Butt will remain part of the Manchester United coaching set-up as the Louis Van Gaal revolution at Old Trafford starts to take shape.

It is thought Butt will return to his role overseeing United's under-21s, alongside Warren Joyce, and managing the under-19 youth team.

The 39-year-old was installed as Ryan Giggs's assistant during the Welshman's brief spell as interim manager last season after David Moyes was sacked as manager in April.

Butt, who made 269 apperances for United between 1992 and 2004 and was a member of the Class of 92 crop, had been kept in the dark over his future after Van Gaal was named manager last month.

But a club source told the Daily Mail that the Class of 92 remained an important part of the Old Trafford club.

"The Class of 92 are very important to Manchester United," the source said. "'Nicky is a member of staff at the club, he has a position here and he is working with Warren Joyce, who will remain at the club."

While Butt's future has been secured, that of another ex-United player remains unresolved.

Former Red Devils defender Phil Neville returned to Old Trafford as part of Moyes's backroom staff and, as well as goalkeeper coach Chris Woods, asked to stay on following the Scot's sacking to work alongside Giggs.

But with Moyes's acolytes now gone, Neville's tenure at the club is up for discussion and it remains to be seen what plans Van Gaal might have for the BBC's World Cup pundit.

Bolstering squad

The news emerged after United finally secured the services of Spanish U21 international Ander Herrera.

The midfielder signed a four year deal at Old Trafford with the option for a fifth after agreeing to buy out his buyout clause.

Luke Shaw is today likely to put pen to paper on a long-term contract that would see the 18-year-old become the highest paid teenager in the country in a £30m deal.

The signings show United's willingness to equip Van Gaal with a squad capable of forcing its way back into the Champions League positions after finishing in a relatively lowly seventh place last season.
