Yes and scored before finals without problems, so it has nothing to do with his ability to finish. Look at the video posted earlier here about his goals in Serie A, they are not easy tap ins, many are scored from tight angles and after great movement. He has similar issue as Suarez to some extent, they can score an impossible goal every game, but if its very simple one on one in a very important game, they just overthink it.
Majority of this forum has 2 reasons why they cannot be objective at all about Higuain: 1) they are Messi fanboys who blame him for the chokes in finals (well its actually entire team to blame, not Higuain, its not like Messi has shined in those finals either) 2) He has Real Madrid backround (which is reasonable reason, but still not enough to be blind about someones capability).
Higuain was by far the best goalscorer in Serie A last season, with this purchase did they not only make themselves so much better vs competition in local league (similar behaviour like Bayern is doing in Germany), but also weakened their main rival.
Great purchase and if they can afford it, why da hell not.
