If the Blues do not want to slip out of the title race, the game against Burnley on Sunday is a must-win for Chelsea, according to Gary Cahill.
Going into this weekend, just two points separate Manchester City in first and Tottenham in fifth, suggesting a tight title race this season.
Cahill insists the title race is too close this season and Chelsea must win games against sides like Burnley.
Cahill told Standard Sport: “It (the battle for the Premier League) is certainly going to be tight this season. As far as the Burnley game goes, these are the matches you need to win if you are going to compete at the top.
“This is a very difficult game – going away to Burnley. Everyone knows that. These are the fixtures you have to churn out the victories in. That is how I have seen it over the years and this season will be no different.
“We are prepared, the form is good, the momentum is good. There is nothing in that regard to fear. We are very respectful of how strong Burnley are at home – they proved that last season.”
Cahill believes it’s too early to predict the Premier League winner because things can happen quickly in football.
Cahill added: “I have been here loads of times and before Christmas you don’t see where it is going to go.
“Arsenal are on an incredible run of form at the minute. When they lost at our place (in August) and already points off the top, people were writing them off.
“All of a sudden they have been in unbelievable form. That’s what can happen. We did it the last time we won the League after losing at Arsenal and at home to Liverpool. Then we won 13 games in a row, which is why people should wait till the new year.
“I think if you are in a good position after Christmas and coming into January, you feel like you have a chance.
“There are loads of games to play until then, a lot can happen. It’s just a matter of going from one weekend to the next and building a momentum.
“It’s great when you go back into training after getting three points. It’s the same going into training today after winning in the Europa League (against BATE Borisov) last night. It’s much better than going in after a loss. That’s why I say momentum is key and we have that right now.”
