He's not finisher, he's nowhere fucking near that.
Based on what man? Let's be honest neither of us have seen much at all of him other than highlight videos. Or I certainly haven't seen you claim to be a follower of his career anyway so please correct me if I'm wrong. His record, especially in the Champions League suggests he isn't a bad finisher at all.
