Arsenal manager Arsene Wenger is confident midfielder Jack Wilshere can return stronger from the setback of facing three months out with an ankle injury.
The England international this week had surgery to repair ligament damage following a tackle by Manchester United defender Paddy McNair during the Barclays Premier League match on November 22.
Wilshere is now set for another frustrating spell on the sidelines, having seen his progress hampered by various problems before and at one point being absent from the Arsenal first team for around 17 months after suffering a stress fracture in his ankle during 2011.
Wenger, though, has no doubts the 22-year-old has the strength of character to overcome his latest challenge.
Arsenal's injury list
Arsenal's injury list
1/5 Mikel Arteta (midfield)
Like Diaby, the Spaniard is closing in on a return but the Swansea match will come to soon. The club captain last played in November.
2/5 Mathieu Debuchy (defender)
Returned in the FA Cup semi-final win over Reading but has since been ruled out with injury and Wenger confirmed he remains 'unavailable'.
3/5 Alex Oxlade-Chamberlain (midfield)
Suffered a hamstring injury against Manchester United in the FA Cup and hasn't played since as it has exacerbated a groin problem. Out at least until May and facing surgery in the summer.
4/5 Aaron Ramsey (midfield)
Aaron Ramsey caught a kick on his calf during the win over Hull and was later substituted. The Welshman was rated 50/50 for the Swansea match by Wenger, but it now appears that he is a major doubt for the clash at the Emirates.
5/5 Danny Welbeck (forward)
Danny Welbeck has not played since the goalless draw with Chelsea towards the end of April after suffering a knee injury. Wenger has confirmed that the injury is 'nothing major', and that he should return to full fitness before the end of the season.
"He is very down. Jack is a football man who loves the game, but on the other hand, he is a very strong character as well and he has learnt to deal with adversity at a very young age," said Wenger, who has a host of fitness concerns ahead of Saturday's lunchtime kick-off at West Brom.
"I think he will be back at the end of February, beginning of March, and he will focus on coming back to rehab, having a strong rehab, and then I am sure he will help us to do well until the end of the season.
"Jack always came out stronger and, when I spoke with him, the final sprint of the season is already in his mind and [he wants] to come back stronger.
"He is prepared and focused to come back and finish the season well."
Wenger believes Wilshere can shrug of the latest in what has been a long line of injuries to hamper his progress.
"I was more worried one year ago than I am today because he had two or three surgeries on his right ankle. At some stage, you could raise that question, but today I am much more confident that he will [fulfil his potential]," Wenger said.
"If he has no problem with his joints, he will make a massive career."
While Wenger feels McNair's challenge was "very bad", he accepts it was "not malicious".
He said: "When you see it again, I don't think that anybody would have escaped without surgery in this tackle."
Wenger does not expect Wilshere's dynamic playing style to change.
"It is his strong point to turn, run at people and be committed - you don't want to take that away from him," he said.
Arsenal will look to bring in "at least one body" to bolster the depleted squad, Wenger confirmed, with a defensive midfielder the expected target with centre-half Laurent Koscielny fit again and full-back Mathieu Debuchy close to a return from his long injury lay-off.
Wenger, though, stated there had been "no enquiry from anybody" for Germany forward Lukas Podolski and denied a move for Chelsea goalkeeper Petr Cech.
The Arsenal manager conceded, however, the set-up of the side would have to be changed, given the loss of captain Mikel Arteta to another calf injury, adding to an already packed treatment room.
"I will adapt because I lost two players who can play in a defensive area in our midfield. We, of course, have to adapt," he said.
Wenger is confident Arsenal can use their midweek Champions League win over Borussia Dortmund to kick-start the Premier League campaign, his side currently in eighth place.
"Even in the games we lost, there was something happening in the team. That, for a manager, is the most important thing," he said.
"I am very positive about this team because there is something special in there and we just have to keep going."
