Arsene Wenger claims his squad has been ‘decimated’ through injury following Arsenal's 2-1 victory over Liverpool.
Mikel Arteta suffered concussion after colliding with Jordan Henderson, which resulted in the Spaniard being stretchered off during the second half as a double from Robin van Persie boosted Arsenal's hopes of securing Champions League football next season.
Substitute Abou Diaby only lasted 27 minutes before hobbling off with a hamstring injury, while Yossi Benayoun and Kieran Gibbs are doubts ahead of Arsenal’s Champions League last-16 second-leg clash with AC Milan on Tuesday.
"The bad news of the day is that Diaby is injured and did his hamstring. Benayoun has a small hamstring problem, Gibbs has a problem," Wenger told the club's official website.
"We look decimated after the game."
Arsenal trail the Serie A champions by four goals after a commanding display from the Italian side at San Siro.
“I don't know who will be available on Tuesday night," said Wenger. "Maybe I will play with six strikers, as we have to score goals!"
