Chelsea captain John Terry has fired a warning to Manchester United that the title race in on ahead of his return from injury at the weekend.
Terry has been sidelined since undergoing back surgery in mid-December but is expected to return when the Blues face Charlton in the Premiership at the weekend.
And the inspirational Chelsea and England captain has challenged his team-mates to overhaul United's six-point lead at the top of the table.
"We've got to make up six points on Manchester United in 13 games - seven really to go ahead," he said.
"What that means is that we've just got to go on winning games because we can't really afford to lose points.
"If we do go on winning games, they can't afford to lose points. The race is on.
"We're in the final of the Carling Cup. We entered the competition to win it and that's still what we intend to do.
"We're in the fifth round of the FA Cup and we've been drawn at home against lower-league opposition.
"If we are not lazy or arrogant or stupid, or extremely unlucky, we ought to go into the quarter-finals.
"The Champions League returns this month and, although Porto may be a better team than when we played them two years ago, we are the group winners and they are the runners-up and we have enough quality and commitment in our squad to win the round.
"So this is the way it is. We believe that we can continue to compete in all four competitions."
