Manchester United continue to be heavily linked with the summer pursuit of Ajax keeper Jasper Cillessen.

According to the Daily Mirror, the Red Devils are pressing on with their chase for the Holland international who is being lined up as a potential replacement for David De Gea.

Cillessen, 26, was United boss Louis van Gaal's number one in the Dutch setup at last year's World Cup in Brazil and it is being reported that his services will cost the Old Trafford club around £20million.

However, Cillessen recently admitted that Ajax boss Frank de Boer would block any move for the former NEC Nijmegen man, indicating it will be difficult to land the shot-stopper in this transfer window.
