Agree with all this. If he can develop a real cutting edge / clinical streak he will be class. He has all the attributes. This is the first time he has played in a good Premier League team, having previously played in the Champ or in the Prem for Birmingham or Norwich. Being around Boufal, Tadic, Van Dijk, Bertrand etc. will help him develop, as will European football.
He was a bargain for the price.
