Manchester United have now set their sights on signing Ajax goalkeeper Jasper Cillessen after reportedly wrapping up a deal for Morgan Schneiderlin, according to the Daily Mirror.

David de Gea's future at the club is still under deliberation, with the Red Devils refusing to sell the Spaniard to Real Madrid at anything less than their valued price, as stated by the Daily Mirror. However, it has not dissuaded them from making a move for Cillessen, who has been earmarked as the rightful successor to De Gea's throne.

The 26-year-old has done well with the Dutch national team under Louis van Gaal at the 2014 World Cup where they finished third and the former Bayern Munich manager is desperate to renew ties with him at United.

However, the keeper admitted that it would be difficult for him to make his way out of Ajax, as manager Frank de Boer has insisted that he will block any move from a foreign club to claim his services.

"The Ajax management are going to make it really difficult when the interest becomes concrete," Cillessen said.

"If I had planned to leave, I would not have signed a new contract until 2018. My old contract was expiring in the summer of 2016 and in that case this summer would have been the perfect moment to leave.

"[Ajax coach] Frank de Boer has been very clear when he received questions about my transfer - he wants to block it," he added.

The Mirror reports that the Red Devils are also keeping an eye on a possible recruitment for Hugo Lloris and Asmir Begovic should a move fall through, but have potent cover in Victor Valdes, who signed from Barcelona on a free transfer last January.

The Spaniard has made only two appearances thus far for the Red Devils following an injury to De Gea against Arsenal, but put in a brilliant performance against Hull City on the closing day to stake his claim on a first team spot.
