Arsenal manager Arsene Wenger has remained positive and optimistic over the fitness of midfielder Jack Wilshere.
Wilshere had surgery on an ankle injury he suffered in the defeat against Manchester United last weekend.
"We knew he would have surgery. He's focused to come back and finish the season well," said the boss.
"His injury is a consequence of a very bad tackle that was not malicious."
"He deals very well with tackles and kicks but nobody would've dealt with that tackle."
"If he has no problems with his joints he will make a massive career."
Wenger also confirmed a fresh injury problem, with Yaya Sanogo struggling to be fit for the game against West Brom.
"Szczesny hasn't trained, Arteta is out, Sanogo has problems and Welbeck will be checked."
"He (Welbeck) had a swollen knee so he wasn't available for Dortmund."
"He (Walcott) has a groin problem that he came back from England with. He's not available."
There was a slight boost on the injury front, with Wenger suggesting that French defender Laurent Koscielny could come back into the team if the boss wants to select him.
"He's well. If I want him to start he will start."
The boss also admitted to some sympathy for German forward Lukas Podolski, who could be drafted into the centre forward role.
"He faces big competition. He has an outstanding attitude and he works very hard - I have had no enquiries from anybody."
Wenger has also praised the desire in his team after they secured a place in the last 16 of the Champions League by defeating Borussia Dortmund at the Emirates.
"I have enough experience to know what's happening. There's life and a desire in our team."
The boss has also confirmed he's analysed the performance against Manchester United and is happy with what he got from his team.
"We analysed the Man United game and there were more positives than negatives."
One of the players who emerged from that performance with some positive praise was Emiliano Martinez, who was solid when he replaced Wojciech Szczesny against United.
"We have three keepers who are challenging. Every time he's played he's done well."
