Nicolas Anelka insists Chelsea can come back from 12 points behind Manchester United to win the Barclays Premier League - because he did it with Arsenal 13 years ago.
But the Blues striker admits the champions will have to win all 17 of their remaining games if they are to overhaul United at the end of the season. Chelsea are currently in fifth place, nine points adrift of the unbeaten leaders, who have a game in hand.
Arsenal languished 13 points behind United as late as March back in 1998 - albeit having played fewer matches - but won 10 games in a row to snatch the title. Anelka believes that with both fixtures against United still to play, Chelsea are not out of this season's race.
"It is going to be tough but anything is possible, even if it is very hard," he told his club's official website.
"We have to win every game from now, and maybe we can do it, but to win every game is hard. Most important is to win against the teams that are around and in front of us.
"At Arsenal in 1998, we had belief because, like I said, in football anything is possible, and if you are winning game after game and others are dropping points, it can happen."
