Paris - Paris St Germain defender David Luiz, who risked long-term injury by playing for Chelsea in the 2012 Champions League final, will not celebrate if he scores against his old club in their last 16 first-leg tie on Tuesday.
The Brazil centre half, sold in June for a fee that media reports put at £50 million, picked up a hamstring injury ahead of Chelsea's penalty shootout victory over Bayern Munich three years ago.
With John Terry and Branislav Ivanovic suspended, Luiz told physio Jason Palmer not to tell then-manager Roberto Di Matteo he was struggling to be fit.
