Pochettino's immediate reaction to Trossard's goal - spotted

Leandro Trossard has given Arsenal the lead against Chelsea. The Belgian bagged his 10th league goal after just four minutes. 

Trossard's fierce shot went right at Djordje Petrovic’s near post at foot level. The goalkeeper should be saving such efforts.

Anyway, we are glad he didn't. Mauricio Pochettino didn't seem pleased, bowing his face in disappointment.
