Wenger wants to finish up with win at Emirates
Arsenal will be out to sign off from their Premier League season with a return to winning ways against West Brom tomorrow, and so take some momentum into the FA Cup final.
Wenger's men laboured through a goalless draw at home to Sunderland on Wednesday night, which was enough to keep the Mackems up and all but secured third place for the Gunners.
"We have fought very hard to directly qualify for the Champions League and we want to get over the line and finish the job, which we couldn't do on Wednesday night. We want to do it in a convincing way on Sunday," said Wenger, whose side have not scored at home for three games.
Arsenal forward Danny Welbeck has been troubled a painful knee injury which could put him in a race against time to be fit for both the FA Cup final against Aston Villa on May 30 and also international duty with England in June.
"Danny will go out today for the first time, we have to wait for the response to that to know if he responds in a positive way. He could be fit very quickly," said Wenger.
"There is a good chance that he will be available for England, however it is difficult to know.
"But certainly if he is not available for the FA Cup final, I can't see him being competitive enough for England."
Wenger added: "Danny Welbeck is not out for a long time and he has nothing at all on any scan, just bone bruising on his knee, that is just the pain that will decide if he is fit or not."
