The 20-year-old winger completed a move to United in January but was immediately loaned back to Selhurst Park. 

He was a key part of Palace's Premier League promotion after they beat Watford in the play-off final at Wembley in May. 

Zaha started 46 games for the London club last season and scored eight goals. 

The immediate future of the young player hangs in the balance, though, as it is has been questioned whether he will continue at Palace or be given a chance at Old Trafford.

Chief executive Alexander told Sky Sports News: "It's another option, clearly that's up to Manchester United. He's their player now. Will we be asking? We'll probably ask in passing but it's really down to them.

"Would we love to see Wilfried back? Of course we would but he's got a career at Manchester United and, after a few training sessions up there, I'm not sure they'll be willing to let him out on loan."

Palace return to the Premier League for the first time since 2005 and will kick off their season with a tough fixture against Tottenham at home. 

Alexander insisted that the side are excited for the challenge and will make the transition in good form. 

"We're really fortunate - we're coming up with a real good squad," he added.

"Most of our team from last year is signed up, they're obviously used to playing with each other, they've got great team spirit and we will be adding to the squad.

"There's a number of names on the list but we've already got the basis of the squad already there. It's difficult to say in terms of numbers - we have got some key areas."
