it could be also due to the way/role he used to play in Italy vs. the role which Mourinho wants him to play at Chelsea might be a bit different and he might find it difficult to adapt
nice compilation...I feel he has improved...became more aggressive on the ball...which is good..but he still needs to improve other aspects like shooting accuracy imo
I am not the expert but I feel dribbling skills are quite difficult to improve at this age ...However he can at least work on strengthening his body and his shots I guess...
