United States goalkeeper Matt Turner has joined Nottingham Forest from Premier League rivals Arsenal on a four-year deal, it was announced on Wednesday.

No fee was disclosed for the 29-year-old, but British media reports said the deal could be worth up to £10 million ($13 million, 12 million euros) in total.

With David Raya set to join Arsenal from Brentford, Turner's first-team chances could have been further limited had he stayed at the Emirates Stadium.

"It is a great challenge and a great step in my career," Turner, who moved from the New England Revolution to Arsenal last June and played in their Europa League campaign, told Forest's website.

"The manager (Steve Cooper) and the backroom staff, everything about the club has a little sparkle to it. It has felt right from the start and I am happy it's got done."
