Sunderland could complete the signing of Robbin Ruiter in the summer transfer window, suggests manager Simon Grayson.
As reported by The Chronicle, the 30-year-old had been on trial with the Championship club following his departure from Dutch side FC Utrecht.
The Dutch goalkeeper played well against Bradford City and Scunthorpe United in pre-season friendly matches, and although he is now back in the Netherlands, Grayson is confident that he will sign a contract as a free agent.

“He was always going back to Holland, he had some issues to sort out over there, but we are talking to his agent and hopefully we might be able to conclude a deal,” Grayson told The Chronicle about Ruiter.

Sunderland will kick off their 2017-18 Championship campaign with a home match against Derby County on Friday evening.
The Black Cats will head into the match against the Rams at the Stadium of Light on the back of a 5-0 hammering by Scottish Premiership giants Celtic at home in a pre-season friendly game.
Sunderland got relegated from the Premier League at the end of last season, but they will be one of the favourites to finish in the top six of the Championship this term.
Grayson has signed Aiden McGeady, James Vaughan and Brendan Galloway (loan from Everton) among other players so far in the summer transfer window.
