The France international is confident the Blues are good enough to win the Champions League title.
The 30-year-old told the Daily Star Sunday: "It's a big target for this club to win the European cup.
"Coming so close has been frustrating and we really do feel this is the year we can win it.
"Any talk of us putting more importance on the Champions League than the Premier League is wrong - we know how important both are to the club and the fans.
"We want them both. We know how hard that will be but we have a fantastic squad.
"The manager can put one team out on a Saturday and another out in the week. They would both be world class."
"I think our manager is one of the most proven managers there is," he added.
"Every single player at the club is having a lot of fun playing under him and he wants the Champions League as much as us.
"This can be the season for us."
