Former Manchester United defender Paul McGrath insists his old club can stop Manchester City's Treble push.
City meet United in the FA Cup final next week before facing Inter Milan in the Champions League final.
"Manchester United are the last team they want to be facing in the FA Cup Final," stated McGrath to the Sunday World.
"On paper, you would say City are big favourites, but this is a match that has to be won by Manchester United.
We all know that City are closing in on the treble and United are the only club to have done that in English football.
"So they owe it to the team of 1999 to go out there at Wembley in the FA Cup Final and stop City winning this treble.
"The history of this great club is on the line here and pulling on that red shirt has to mean a lot to the United lads who will go out at Wembley to take on City.
"If they are as motivated to make sure United are still the only club to do a treble, then City will have a hard time in the FA Cup Final."
