Arsenal without key quartet for match at Porto

Arsenal will be without Eduardo da Silva, Andrey Arshavin, Manuel Almunia and William Gallas for Wednesday's Champions League match at FC Porto.

The quartet did not travel with an 18-man squad when it departed for Portugal on Tuesday.

Eduardo has not played since the 0-0 Premier League draw against Aston Villa on Jan. 27 because of a hamstring injury, while Arshavin picked up a similar problem against Liverpool last week.
