North London giants Arsenal have so far been frustrated in their pursuit of Crystal Palace winger Wilfried Zaha and Manchester United have played a big part in that.
Crystal Palace have already rejected a £40m bid from Arsenal for Zaha and they are holding out for twice that amount if they are to sanction his exit.
The Eagles are under no pressure to sell their star player this summer.
Wilfried Zaha signed a new contract at the club last summer and that has prompted senior club officials to slam an asking price of £80m on the Ivorian international player.
Crystal Palace are not willing to lower their asking price for Zaha due to the 20% sell-on clause from Manchester United.
The Red Devils initially signed Zaha from Crystal Palace in 2013 only for the player to return to the club two years later on a permanent deal after his unsuccessful spell at the Theatre of Dreams.
Manchester United inserted the aforementioned sell-on clause into the £6m deal for Zaha in 2015 meaning that the Red Devils are entitled to 20% of the profit (£74m) if the player moves to another club for the said £80m.
The Red Devils would be due by £15m from the proposed transfer.
