Leaders Chelsea opened up a gap of over ten points following their win against Tottenham Hotspur and Allardyce is of the opinion that the Blues have done enough to maintain their place at the top of the Premiership for the rest of the season.
The Trotters boss beleives that it will be a tall order for anyone to catch Jose Mourinho's team unless they throw it away in the final four months of the season.
"It's a tall order for anyone to catch Chelsea now, It's all about Chelsea throwing it away from this position. I can't see them doing that with their squad and their determination.
"Chelsea keep clean sheets and that is the foundation for any success. There is no better way to win things."
