Chamakh has admitted it has been a difficult time in the last few weeks for the club, but he believes they have the quality to claim the Premier League crown.
"It's true that we are currently in a difficult period: we're out of the Carling Cup, the Champions League and now the FA Cup," Chamakh told the club's official website.
"The final thing for us to focus on is the League and, knowing the lads and the qualities we have, I think we can win it.
"There are 10 games left until the end of the season, there is no longer any room for failure, we have run out of excuses as we are out of all three Cups.
"We are frustrated but we can win this title this season. It's the right time. This is the last stretch of a long road to the title and we need to work hard."
