Chelsea skipper John Terry has insisted that Manchester United can be caught in the title race and that they are "not invincible".

The Blues are in serious danger of losing the title this season, with their grasp on the trophy all but diminished as they trail the Red Devils by 12 points in the Premier League.

After such a strong start to the campaign, Chelsea have come off the rails in recent months, winning just five of their last 16 matches and seemingly suffering from a lack of confidence.

It has not been a vintage season for United either in the quality of their performances at times, particularly away from Old Trafford.

However, they have shown great resilience and maintained a winning mentality to stay top of the division, having only lost their first game of the campaign to Wolves at the start of February.

Chelsea boss Carlo Ancelotti is under serious pressure to improve results, having spent over £70million on Fernando Torres and David Luiz to bolster their squad at the end of January, though an upturn has not been instant.

Terry accepts that the chances of retaining the title now are "really small," but feels that a 12-point lead is not unassailable, as demonstrated by United's victory over Newcastle in 1996 when they came back from a similar deficit.

"It's been done. Man United did it to Newcastle many years ago," the former England captain said. skysports.com
