I thought it was a wrong buy in the first place. Because he's overestimated, he still had to make it into world class instead of Porto, AM and Monaco which are not. If you watch an in form striker in a super cup and lots of his goals on YT it's easy to be impressed, but his first touch has never been solid and it's never been much else but a finisher. Therefore as a type of striker he'd never fit in perfectly, and on class it also was a bit iffy, and then there was the injury and the fact that the EPL has different demands, it could have worked out but it was very unlikely to begin with.
But even in the most difficult spells for him, he didn't hide but kept doing the things he should be good at. So I hope he finds a nice club, and ends up like a Forlan or Battistuta or something.
