Chelsea boss Rafa Benitez won't be complacent with his team selection for tonight's Europa League semifinal second-leg clash with FC Basle.

Chelsea will be defending a 2-1 aggregate lead.

Benitez insists he will take no chances with his line-up tonight, even though David Luiz, John Obi Mikel, Ramires and Ryan Bertrand are all one booking away from missing the final.

He said: "The main thing is to win and qualify for the final, so we will try to put out the best team possible. The yellow cards don't matter."
