Arsenal's injury crisis is showing no signs of easing as Arsene Wenger confirmed that the trio of Nacho Monreal, Kieran Gibbs and Alex Oxlade-Chamberlain all suffered knocks in the win against West Bromwich Albion on Saturday.

The Gunners' injury troubles are only getting worse following injuries suffered by Jack Wilshere and Mikel Arteta in the games against Manchester United and Borussia Dortmund respectively. The former is set to be sidelined for at least three months after having surgery to repair damaged ligaments to his ankle and the Spaniard is also reported to be out for at least four to six weeks with a calf injury.

Monreal, was the first casualty after picking up a knee injury early in the first-half and was substituted in the 22nd minute, his replacement Kieran Gibbs, who has been in good form off late picked up a knock on the ankle and was a little laboured during the second half, similarly his compatriot Oxlade-Chamberlain was brought down by a robust tackle from Georgios Samaras and left the pitch after the game complaining of knee pain.

"Gibbs struggled a little bit with an ankle problem and Monreal with a knee problem. Oxlade-Chamberlain also had a knee problem," Wenger said, as quoted on Arsenal's official site.

The trio, who suffered knocks against the Baggies, will be assessed ahead of Arsenal's crunch fixture against Southampton on Wednesday night. It is a fixture the north London club will be keen to win, as they need to start making up ground on the Saints, who are currently second in the league six points ahead of the Gunners with a game in hand.

Wenger was unsure of the extent of the injuries suffered by his players and will wait till Monday to see how they recover to make a decision on whether to play them against the St Mary's outfit.

"I don't know. We have to see how they recover on Monday. We have Oxlade-Chamberlain, Monreal and Gibbs who have knocks but I don't know how bad it is," the Frenchman added.
