One player who has been on many people's list of those exiting Stamford Bridge in the summer is defender and midfielder David Luiz.
Despite being somewhat of a fan favourite for the Blues, as well as an integral first team player under former managers Rafa Benitez and Roberto Di Matteo, Jose Mourinho has often exuded a certain reluctance with the Brazilian, who has fewer appearances to his name this season than he managed during his other years at Chelsea.
However in recent weeks Luiz has excelled in the defensive midfield position Mourinho seems happy to employ him in, and despite a difficult match in Paris last week, where the former Benfica man scored a poor own goal, Luiz may have convinced his boss that he is a man worth keeping with a dominant performance in the return leg.
Luiz was everywhere against the French champions, winning tackles, calm under pressure and distributing the ball superbly to minimise the threat Cavani and co posed to the Chelsea back line.
It was a performance that didn't go unnoticed by Mourinho, who on describing the team's performance was quick to praise Luiz.
"We gave everything," the Portuguese gushed to Sky Sports. "My four defenders were brilliant. The midfield were animals. Luiz was a monster. Our forwards were brave."
Is that a monster Chelsea could hand out to one of their European rivals? It may depend on what happens to Barcelona's transfer ban, but it's already looking increasingly unlikely.
