The thing is, every club will have fans who scrutinise their players and see all the imperfect/bad things they do. But if the stats read impressively - he's a winger and he's near top of the assists league, rival fans/neutrals will assume that he's one of the best players in the league. The truth is probably in between - he could be a lot better, but for our current level, he's more than adequate most of the time.
