Arshavin questions Arsenal big-match mentality
He told The Sun: "What I feel bitter about is that we lose in all the big matches.
"That is disappointing and lets doubts creep into my mind.
"Chelsea are now 11 points ahead of us, although we played one game less. At the moment, they look the strongest team.
"They have attacking players who can make use of opponents' slightest defensive mistakes.
"Didier Drogba, for example. If we only take pure strikers, he is the strongest in the world. He and Zlatan Ibrahimovic."
