London: Arsenal forward Andrei Arshavin said he would miss Wednesday`s Champions League game at Porto with a hamstring strain.
Arshavin picked up the injury in last week`s Premier League win over Liverpool.
"If all goes well I get back on the pitch as early as the next Premier League match against Sunderland. However, the next game against Porto I will miss," the Russian told the league`s official website.
Alex Song is also struggling to make the Porto match after injuring a knee in the same game.
