Manchester United must go to £15 million to sign Crystal Palace winger Wilfried Zaha.

United will have to pay ­£15million including add-ons AND allow ­Zaha to stay at Selhurst Park for the rest of the season to sign the Crystal Palace whizz-kid, says the Sunday Mirror.

Sir Alex Ferguson has been making his own checks on Zaha and his personal ­intervention in the process suggests that United are ready to increase their initial bid of £10m.

The United boss has spoken to a number of people who know the 20-year-old winger both professionally and personally.

And the message back was that Zaha has the mental attitude as well as the technical aptitude to be a success at Old Trafford.
