Manchester United boss Louis van Gaal wants goalkeeper David de Gea to put an end to all the speculations on his future and decide whether he wants to leave this summer.

The Spain goalkeeper, whose current contract is set to expire next summer, is yet to sign a new deal at Old Trafford even though the Red Devils are reportedly offering him a new contract believed to be around £2,00,000 a week.

As a result, his future at Manchester United has been subject to a lot of speculations, with Real Madrid believed to be keen on bringing him in as a replacement for their ageing goalkeeper Iker Casillas.

Although Van Gaal admits that he does not know when De Gea's future will be resolved, he insists that the goalkeeper, who missed United's final game of the season against Hull City due to injury, will have to soon make up his mind on whether he wants to stay or go.

"I cannot say when it [De Gea's future] will be resolved. He has to say something," the Dutchman told BBC.

Although signing a new goalkeeper is currently not one of van Gaal's main priority this summer, he may be forced to look at possible options of De Gea does leave this summer.

Chelsea's Petr Cech, who is expected to leave this summer after being displaced by Thibaut Courtois this season, could be a potential candidate to replace De Gea despite Jose Mourinho insisting that he will not be selling the veteran goalkeeper to a Premier League rival.

Meanwhile, former Manchester United striker Andy Cole feels that the Red Devils should again target a top four finish in the Premier League next season as he believes that winning the English title will be "very, very tough."

"The aim should be the same again -- to finish in the Champions League," Cole told ESPN. "To win the Premier League next year would be very, very tough."

"Chelsea have been the best team. In the first half of the season they played very well and in the second half they ground results out. How many teams can do what Chelsea do? There are going to be the team to beat next season."

"If you miss out for two years it gets harder and harder. It will be tough for Manchester United to win the Premier League next year."
