3) Defenders won’t cope with Costa
Perhaps the key player for Chelsea for this fixture, as indeed for many of their games this season, Diego Costa is the best striker in Europe this season and will surely prove too much for PSG’s defence. Former Blues ace David Luiz is up against his old club and has mistakes in him which Costa will exploit, while Thiago Silva also looks somewhat past his best. They won’t come up against many players as good as Costa in Ligue 1, and it certainly seems like the Spaniard could make the difference in this tie.
