How is he overrated? He's about to be promoted for the second time in 3 and a half seasons in the championship. He's the perfect player at this level and is showing it. He's scored 13 goals and got 8 assists. Matt Ritchie has 11 goals and 7 assists to compare.
Maybe I should have said that "he's overrated by some people on here". Some are even mentioning him as a signing for the PL, for what he'd cost we could get better easily Imo. He's been poor for Brighton in quite many games from what I've read on their forum during the season, that he often tries to do the same thing over and over despite that it isn't working in some games and that he should look to have some variation at times. Yes he's the kind of player that needs to try and should be allowed to fail and all that. But he's not all that from what I've seen (which isn't every game tbf). Having said that, yes he's a good player at this level, no doubts about it, but also overrated to some degree. I might be biased but I think Ritchie is the better player, but that's just my opinion.
