Manchester United have been boosted in their attempts to sign Palermo's Paulo Dybala after the Serie A side President Mauro Zamparini admitted that the striker may be leaving the club after the end of the current season.

The Red Devils were being linked with a January move for the 21-year-old striker, who is being dubbed as the "new Sergio Aguero", but Zamparini recently insisted that Dybala would not be allowed to leave in the winter transfer window.

However, Zamparini despite confirming that his side are close to extending Dybala's contract by a further three years, expects the striker to move to a bigger club in the summer.

"This week Dybala will sign a new three-year contract with us," Zamparini told Rai radio. "If he does well in the next six months then surely the next summer a big club will buy him."

"He can play, in order, in England, France, Germany and Spain. I say Spain last because the top teams Real Madrid and Barcelona are covered with good strikers."

However, Zamparini insist that the Argentine will not be available cheap.

"This renewal is also for his own good. He is destined to go to a great club. It's useless to talk about a price. With Zamparini, it is always expensive."

"I think Dybala is one of the best talents in the world. He is a team player, but he still has to grow for another four or five years."

The Red Devils will certainly not be able to secure the signature of the Argentine striker, who has already netted 10 goals in 18 Serie A appearances this season, that easily as a number of top clubs including Paris Saint-German, Liverpool and Arsenal are also believed to be keen on landing him.

Meanwhile, former Manchester United defender Gary Neville has urged Red Devils boss Louis van Gaal to do away with the 3-5-2 formation and stick with four players at the back.

Although United started with the 3-5-2 formation against Queens Park Rangers on Saturday, it was only after the Dutchman reverted to four players at the back that Marouane Fellaini and James Wilson scored and sealed the three points at Loftus Road.

And Gary Neville feels that van Gaal should stick with four players at the back.

"Louis van Gaal wants them to recycle the ball and switch the play. I'm not a fan of 3-5-2 because the centre-backs are the free men and they become the safe option," Neville told the Daily Mail.

"They play out from the back but the tempo is too slow. Far too often they are keeping possession and passing it backwards. They've become quite predictable in the past few weeks. Manchester United looked far more dangerous on Saturday when they changed the system."

"Fans want them to go 2-0 up and then keep possession rather than fight for goals near the end."
