De Boer worried star goalkeeper will join Man United this summer

Ajax manager Frank de Boer is worried about star goalkeeper Jasper Cillessen’s future with club amid interest from Manchester United, according to reports on talkSPORT.

With David de Gea set to join Real Madrid before the end of the transfer window, the Red Devils are frantically trying to find a replacement for the Spain number-one.

This has seen the likes of Tottenham Hotspur’s Hugo Lloris, Galatasaray’s Fernando Muslera, and Cillessen all being linked with a move to Old Trafford.

However, De Boer is keen on keeping Cillessen at the Amsterdam Arena ahead of the Eredivisie season, but he knows that he may have no control over the situation.

“If it takes a long time before it happens, we are increasingly in trouble,” De Boer told Ajax TV.

“We will keep ourselves tight together, unless there is something incredible, but it is not true we have replacements in line.

“We’d love to keep Jasper. I do not expect him to go away, but that is my hope.”

The 26-year-old rose to real prominence when he was named as the Netherland’s first-choice goalkeeper during the 2014 World Cup, which saw the Oranje finish 3rd in the tournament.

Last season, Cillessen made 43 appearances in all competitions for Ajax, keeping 16 clean sheets.
