Chelsea played PSG today in a pre-season 'friendly', which was decided in a thrilling penalty shoot-out on their US Tours. While a lot of attention was on Falcao making his Chelsea debut, Chelsea's first choice striker Diego Costa was back in controversy.
Costa clashed with PSG right-back Serge Aurier during the game, when Aurier appeared to lash out at Costa.

Replays revealed that Costa elbowed Aurier in the fact before Aurier retaliated, and while he shouldn't lash out like that - Costa's elbow was very much uncalled for.
Still though, this is the sort of clash that shouldn't really be in 'friendlies'.
