Arsenal's hopes of domestic and European glory have been dealt another setback as Russian playmaker Andrey Arshavin confirmed he expected to miss up to three weeks with a calf problem suffered in the dramatic 2-2 Champions League quarter-final clash against Barcelona.
The Gunners are anxiously awaiting the outcome of scans on captain Cesc Fabregas, who fears his season - and possibly World Cup hopes - may be over after suffering what could be a broken leg as his side battled back from 2-0 down to snatch a draw to take to the Nou Camp next week.
Defender William Gallas, meanwhile, looks set to also be unavailable for the remainder of the campaign after he broke down on his return following eight games out with a calf injury.
Arshavin was substituted inside 30 minutes at Emirates Stadium last night, and believes he will now spend the best part of a month on the sidelines - missing not only the return leg in Barcelona, but also the north London derby at Tottenham on April 14.
The Russian said on his personal website, www.arshavin.eu: "Perhaps I won't be able to play for another two or three weeks.
"It is not a relapse of my old injury, this is a new one."
Arshavin, however, maintains his team-mates have what it takes to pull of a shock victory in Spain.
"The rest of the players will play to win," he said. "They showed great character. Barcelona had a good start, but we found our way back.
"There is one more match ahead, and there is still hope."
Wenger does not expect to have Gallas, 32, available again.
"The rest of the season is compromised for him," the Gunners boss told French TV station Canal Plus.
"He pulled his calf again, so it was a gamble that probably didn't pay off.
"It is the end of the season - I am talking about Arsenal, but I think he will be ready for the World Cup."
Wenger, however, hopes Holland forward Robin van Persie could be back in action by the end of the month after suffering what turned out to be a serious ankle injury while on international duty during November.
The Arsenal manager said: "The latest news on Robin van Persie is very promising, but we have to wait two more weeks to integrate him fully into first-team training.
"Let's hope we can give him some big games to aim for at the end of the season."
Arsenal resume their Barclays Premier League title race with the visit of Wolves on Saturday.
With leaders Manchester United hosting Chelsea, the Gunners could close the current gap, which stands at four points, with victory over Mick McCarthy's relegation battlers - who have won two of their last four games to pull clear of the drop zone.
