Chelsea star Cesar Azpilicueta is under no illusions about the challenge of facing Sevilla.

The Blues are set to take on the UEFA Europa League winners in the Champions League Group stages.

Sevilla defeated Manchester United and Inter Milan on the way to winning that trophy, and will want to claim another big scalp in midweek.

"Since I arrived here in 2012 I always had the belief and the confidence that we could fight for everything," said Azpilicueta to reporters.

"So this year it's true that we didn't start the way we wanted in the Premier League and the Carabao Cup but the Champions League starts, it's completely a new challenge and we have to be ready for it because we are going to be playing against a strong team.

"We saw Sevilla beat Wolves and Manchester United in the last campaign in the Europa League, so we have seen that they have the level to compete against teams in the Premier League, and they are a team that want to control the game offensively and defensively.

"When they don't have the ball they want to get it back and attack quickly and also they try to put their attacking players in dangerous situations.

"Last season in La Liga they finished in the Champions League places and they won the Europa League, so they had a very good season and they have started this season in the same way. We expect a tough game but we are Chelsea, we are at home, we are playing our first game in the Champions League, so we have to be ready to compete."
