Chelsea's interim coach Guus Hiddink promised Manchester United a fight to the finish after Frank Lampard kept their marginal title hopes alive with a stoppage-time winner against Wigan.
The 2-1 win left Chelsea seven points behind United, who also have a game in hand on the Blues, but Hiddink is refusing to give up on their title dreams just yet.
"I am realistic and we have to win our games first," said Hiddink. "Hopefully they will be a little bit more comfortable than this."
The Dutchman has now guided Chelsea to three straight wins since he agreed to become caretaker coach until the end of the season.
John Terry had put the Blues in control with a 24th minute opener but Olivier Kapo equalised with nine minutes remaining. However Lampard headed a last-gasp winner and although it remains a long shot, Hiddink is refusing to give-up on the Premier crown.
"Man Utd are in a good seat but as long as we have a possibility and it is not decided, we will fight and that is what the team showed at Villa last week and again against Wigan," he added. "As long as the team is keeping up this fighting spirit, we keep on going for the things that can be reached.
"Wigan deserve a lot of respect for the way they played. They are hard-working and disciplined and play decent football. They caused us lots of problems."
Wigan boss Steve Bruce claims referee Lee Probert failed to spot a push by Lampard on Mario Melchiot before he headed the winner.
"I thought we deserved something but we didn't get it unfortunately," said Bruce. "In my opinion the referee has made a poor decision. He is only 15 yards away from it. Frank has obviously got his hand in Mario's back and he has turned him round as he's gone to head it.
"We don't seem to get these decisions in big games, on a big stage. We need the referee to be strong and not to get influenced."
