William Gallas believes his side are a “tight-knit” unit who can still challenge for trophies this season.

The 31-year-old scored just after half-time in midweek to give Arsenal a 2-1 lead in the North London derby. Arsène Wenger’s side went on to lead 4-2 but were pegged back by two Tottenham goals in the final few minutes.

As a result, it has been a soul-searching few days for the Emirates Stadium club but, even though he will miss the game at Stoke on Saturday, Gallas wants his side to come out fighting.

“We know we should have taken all three points on Wednesday night but it did not happen,” he said. “I know it doesn't feel like it but we got a draw. It was the minimum we deserved.

“But we cannot dwell on one game. We have to stay focussed on what is ahead of us and not what is behind. We are a tight- knit unit working together with belief and desire to challenge for trophies.  We can do it.

“That starts tomorrow at Stoke. Unfortunately a scan has revealed that I have pulled my hamstring so sadly I won't be involved but the boys are determined to come back with three points. 

“We showed our patience, commitment and skill against West Ham and we can do it again, one game at a time.  We are in this race and want to stay in it and will give everything, that is the least our fans deserve.  They were tremendous on Wednesday night and we want to repay their unwavering support.”
