Nunez potential is not hiding at all,he has been phenomenal ever since his days at Benfica,he scored goals on regular basis.I love the way he plays and connects with other players in the team.we all wait to see what he will be able to do in the premier league.He is a very good player,we know but premier league will test his abilities.
Of course pre-season games are different from official games. And maybe things are a little more difficult at first for Nunez. But I believe that the coach will work well with the player, for in some days he will be an incredible player.
