Arshavin insists Arsenal will fight to the end in the title race.
"Experience tells me we should not go crazy (over recent defeats)," he said. "We have to train, to give 100 per cent in matches, then success is sure to follow.
"Manchester United outplayed us in midfield, controlling the ball and not allowing us to attack, but Chelsea were a more experienced and more powerful team, compared to who we were physically inferior.
"If you choose only between those two, then Chelsea will be champions."
