Russia international Andrey Arshavin has ruled himself out of Arsenal's Champions League last-16 first leg clash against FC Porto because of a hamstring strain.
The former Zenit St Petersburg star picked up the injury in the 1-0 win against Liverpool six days ago at the Emirates Stadium.
He said: "If all goes well I will get back on the pitch as early as the next Premier League match against Sunderland."
Alex Song could miss out against Porto because of a knee injury but Arsene Wenger is expected to recall Eduardo who has been sidelined since the end of January with a hamstring problem.
Meanwhile, Belgian defender Thomas Vermaelen has admitted that he is still suffering pain from the knock he suffered during last month's goalless draw with Aston Villa.
There had been fears that the 24-year-old had broken his leg in the incident but he was able to play the full 90 minutes as the Gunners were beaten by Manchester United just four days later.
"It turned out that I could play against United, but after that game I had some more problems, so I went for another scan," he said.
"We could see then that there was a big bruise on the bone, and that's all. So it is painful but that can be controlled with medicine and, when it is not broken, you can't do too much wrong.
"It is not a big problem to play - yes it is still there and will take some time to go away, but it is not dangerous."
