My point is that it's the type of player he is, rather than his level, that has made a clear difference. His level obviously doesn't hurt!
I make this point because I think a similar solution could be found for the right wing; we don't have to get 120 euro player there because what we're missing isn't the quality, it's the type of skillset. We need someone pacy, with a will to run with the ball and commit players, making more space for Cavani and the left winger. Of course, getting a player with those attributes who is also world class would be a bonus, but not a necessity. Look at Liverpool's front three.
