Chelsea boss Mauricio Pochettino insists they're serious about competing for the Carabao Cup.

Chelsea meet Blackburn Rovers tonight in the fourth round.

"I told you before, at the start of the season, a competition like the Carabao Cup or FA Cup is really important for us," said Pochettino.

"Tomorrow, we will try to play with our best team. Some players we will need to rest because after Saturday's game we can't take risks. But in general, we will try to play our best team.

"All the players need to be ready to play tomorrow, and then we will decide. We are going to take it very seriously because we want to go far. This is a competition we can go through in.

"It's important for us to go forward in this competition, to build momentum, and after go to Tottenham and receive Manchester City with the trust and the confidence we can beat them also."
