Bacary Sagna
Sagna is a doubt for the visit of West Brom.

Arsenal defender Bacary Sagna is the latest player to join the club's growing injury list after being ruled out of the Premier League visit of West Bromwich Albion due to a knee problem.

The Frenchman has been the mainstay of the Gunners back four this term but is expected to be absent this weekend in order to ensure he is fit to feature in the FA Cup final against Hull City.

Jack Wilshere, Alex Oxlade-Chamberlain and Kieran Gibbs have all been ruled out of the game on Sunday against the relegation-threatened Baggies, where a win would secure Arsenal Champions League football for a 17th consecutive campaign.

Wenger said on Friday: "Sagna is a doubt for Sunday. We are picking from the same squad as Monday night. Kieran Gibbs is close, Wilshere is not far away. Both close to full training.

"The same group of players [who played against Newcastle United] should be available for Sunday. It's our last home game and you want everybody available and finish with a win.

"Gibbs will be a bit short for Sunday," Wenger added on Thursday. "The good news is that he's back in fitness training but he is not back in the full training group yet.

"They are not ready yet. Alex is in treatment at the moment and not in training. It's very difficult to give you a time-scale on him at the moment."

Though Oxlade-Chamberlain has been ruled out until the end of Arsenal's season with a groin problem while Wilshere continues to recover from a broken foot, Wenger is confident both will be fit to be included in England's World Cup squad.

Ahead of the FA Cup final against Hull City on 17 May, Arsenal can secure a top four spot ahead of Sunday's meeting with West Brom should title-chasing Manchester City beat Everton.

The north London club are expected to be busy in the summer transfer window, but the future of Sagna is still yet to be settled, with the French full-back out of contract at the end of the season.

But Wenger has signalled his intention to keep his prized assets, by stating: "We want the players to stay here because this club has big ambitions for the future."

The club continue to be linked with out-of-favour Real Madrid striker Alvaro Morata but Wenger is adamant Arsenal are not monitoring the Spaniard. "We are in for nobody at the moment," the French boss said.
