Manchester United are due a bumper windfall should Crystal Palace sell Wilfried Zaha this summer.
The Mirror says United never saw the best of Zaha.
The Red Devils splashed £10million to land the winger from Crystal Palace, only to sell him back to the Eagles for just £6m seven months later.
But United always knew Zaha could well still make it to the top - and they were shrewd in their business when they let him go.
It has been widely reported that the Red Devils inserted a sell-on clause in the deal worth up to 25% of his next move.
And that could give Ole Gunnar Solskjaer a major transfer boost this summer as he looks set to finally leave Selhurst Park for a new challenge.
