Arsenal trio to miss Champions League match

Arsenal forwards Theo Walcott and Gervinho, and defender Laurent Koscielny will miss Wednesday's Champions League match at Emirates against Olympiacos, manager Arsene Wenger revealed Tuesday.

Walcott has a knee injury, Gervinho has a muscle strain, and Koscielny has an ankle problem, leaving Wenger without three regulars midweek. All three could return for Sunday's English Premier League match against Tottenham.

Wenger said Walcott has "no damage in the knee," while Gervinho's problem is "very, very mild." He added about Koscielny that he "is not fit."

Arsenal sold Cesc Fabregas to Barcelona and Samir Nasri to Manchester City in the summer, and English midfielder Jack Wilshire was lost for five months this week after having ankle surgery.

In addition, Sebastien Squillaci is not fit, compounding Wenger's problems.

Arsenal tied Borussia Dortmund, 1-1, in its Group F opener in Germany in the Champions League, and sits just 13th in the Premier League.
