I always found Ibrahimovic overrated throughout his career, and it was no different here. It was cool seeing him play for us, and he did have some good performances with one great one against Southampton in the final, but, overall, I thought his general play was lacking. Despite his size and impressive technique, he wasn't that good at keeping the ball under pressure, which was a problem because he loved holding onto it for long periods. On top of that he missed so many sitters and was non-existent out of possession in terms of workrate. Understandably so.
I still have fond memories of him, though, and am glad we got to see him here for one season. I wouldn't change the transfer. One of my favourite memories of him was an away game - I forget who against - and we were trying to see the game out and Zlatan took it upon himself to play as our DM which was fun.
I was actually more impressed with Cavani here but I think I'd still choose Zlatan. Not just the trophies he contributed to, but he seemed to genuinely enjoy playing here. In contrast to Cavani who didn't seem to have his heart in it here despite, when on the pitch, giving it his all.
