I voted for Silva. For most of the season, i was thinking i would be choosing Raheem. He not only recovered from a very difficult summer, but he was improving week-on-week. His form has dipped since March though and in this last part of the season he's looked noticeably less effective than Sane on the other flank which hasn't done him any favours.
Silva has had some terrific games and is such a joy to watch. He fully deserves the recognition. The fact that he's the only player that has hasn't really had a period where he's struggled for form or fitness just makes voting for him a bit of a no-brainer really.
