The Blues find themselves 11 points adrift of league leaders Manchester City following their third consecutive stalemate in Monday\'s west London derby.Chelsea manager Andre Villas-Boas has conceded that the Blues are out of the title race this season, following Boxing Day\'s 1-1 draw with Fulham.The west London outfit were held to their third consecutive stalemate by their local rivals at Stamford Bridge, after Clint Dempsey cancelled out Juan Mata’s opener, leaving them fourth in the table and 11 points behind leaders Manchester City.Following the result, Villas-Boas has admitted that his side face an uphill task to catch Roberto Mancini\'s side, and may not be able to win the Premier League this campaign.\"Maybe the Premier League is over for us at the moment,” he told reporters.\"You have to assess things as they are. There\'s no big drama in terms of how we look at things.\"But you have to be sufficiently real. You cannot live under false expectations when the gap is this big.\"The difference between us and the top is big. We had reduced it to seven points recently but with City and United continuing to get the points they are getting at the moment, it\'ll be difficult.\"You cannot say it is impossible but we have to focus on our position at the moment and make a real assessment.\"We\'d targeted the December fixtures as an ideal situation to find out what would happen in the Premier League. We continue to do that. If we had a good December, it might have been different but if City and United do their jobs, it\'ll be very difficult for us to win it.\"
