Defeats to Manchester United and Chelsea in their last two outings have left Arsene Wenger's side nine points adrift of the table-topping Blues.
The Gunners have suffered significantly with injuries to forwards in 2009/10, with dimunitive Russian Arshavin forced into an unfamiliar centre-forward role following the loss of Robin van Persie, Eduardo and Nicklas Bendtner.
"In football, anything can happen. Stumbles, such as Chelsea losing to Everton, are quite possible. Then there is Chelsea's match against Manchester United [in April] when at least one rival has to drop points," he said in the Mail.
"For us, the main thing is to win our matches. The next one against Liverpool will be key. If we win, we have the chance to make up ground on the leaders and think about the title race.
"If, however, we continue our run of failure, we have to think about how we preserve what we have already got."
