Their impressive 4-1 victory at Stoke City on Saturday followed similarly convincing 2-0 wins against Southampton and Manchester United respectively.
"It was just a kick on his thigh so it is possible he will be available".
He is likely to miss the rest of the season, but Wenger is hoping to have him for the FA Cup final against Chelsea on 27 May.
Sanchez has started all but two Premier League games this season, scoring 21 goals and providing ten assists.
Nevertheless, Wenger was keen to point out that his focus on a prize he last lifted in 2004 remains unwavering. I believe he has become a complete player and developed very well here at Arsenal.
You just want your team to play well.
"Alexis Sanchez will have a test today".
Things are looking up for Arsenal as the team makes its traditional end-of-season charge for Champions League qualification from the English Premier League.
City has 72 points, Liverpool 70, and Arsenal 69.
"You will always have regrets because you could have one point more but you forget as well the games you won in the last season where you could the season after not win". "And we kept a clean sheet again".
"After a hard period we could have got divided but we have chosen to be united and that's what you see on the pitch", he said.
"He got that goal and their fans got a bit louder, so we showed a bit of character to stay in the game when they had seven corners in a row", Holding said. "Overall, the only chance we have to be in the top four is to win our games".
Arsene Wenger refused to criticise West Ham for their feeble performance against Liverpool which looks set to cost Arsenal a place in the Champions League next season.
It's now highly unlikely that Arsenal will finish the season in the top four. "It will be hard to swallow but it wont completely change the judgement of the team".
We have to improve and be determined at Arsenal.
"It's a hamstring problem, but we don't know how bad it is".
Arsenal beat Chelsea 3-0 at home in September and had looked serious title contenders.
Arsenal still count every game as a sell-out and announce their attendance figures based on tickets sold.
Asked if it had been unfairly rough, Wenger said: "I don't say that".
When a reporter pointed out that patches of empty seats can be seen at games, Wenger added: "Yes, but that doesn't mean we are not sold out".
