I'll add a more general comment, Coutinho is more like Luis Garcia, very wasteful in possession considering all the good positions he has the ball in, saved by the fact that once in a while a shot isn't wayward.
Nah, Coutinho on an average day is like Luis Garcia.
Coutinho on a good day can be the best player on the pitch and this is whilst playing the likes of Arsenal, Man City and Chelsea (when the latter two were good).
