We should get Paul because we have a weaker midfield then attack. But I hope people realise that Neymar is a much better player and would have significant impact on this team like no other player, not named Messi (we already have Ronaldo).
For the same cost I'd rather Neymar, always, they're players of completely different magnitude. But if Pogba comes at half the price, probably rather him, as we do need a mid type like him.
