• Wenger reveals he will extend deal in radio interview • 'I want to continue where I am … that means to stay'

Arsène Wenger has promised Arsenal he will sign a new deal to stay on as manager beyond this season, he revealed on Friday.

The Frenchman's contract runs out in the summer and an extension has remained unsigned as Arsenal's Premier League title challenge has unravelled in recent months, leading to suggestions Wenger might be ready to leave after 18 seasons in charge.

However, the 64-year-old now looks certain to extend his tenure at the Emirates Stadium after a season which could end with the FA Cup trophy.

Asked in an interview with beIN SPORTS, broadcast on Talksport, whether he would stay or go at the end of the season, Wenger replied: "Look, I have said that many times already, I have given my word to this club and that I want to continue where I am … that means to stay."

Arsenal host Newcastle on Monday night, looking to cement their place in the top four of the Premier League ahead of Everton. Thomas Vermaelen is expected back from a hamstring problem but Abou Diaby will not be rushed into a return from a serious knee injury. He reported a slight groin problem after playing for the under-21s in midweek, his first action since suffering a cruciate ligament injury against Swansea in March 2013.

"Diaby played one half [for the under-21s]. How far away he is is difficult to say, but he had a little groin problem after the game so will not be available for Monday," said Wenger.

Kieran Gibbs is still sidelined by a hamstring problem, while Jack Wilshere continues his recovery. "Jack is progressing well. He is still on target to be with our team in the last couple of games," Wenger added.
