Personally do I think he suits Villa, No, not now, that ship has passed. But there’s no guarantees Watkins will take a step forward in his second season in the PL also. Watkins is far from the finished article, he needs competition to push him and we need a player on the bench who can change things up front when Watkins isn’t getting the goals. If we are serious about the Top 6 then it is needed.
At the same point Smith got the best out of Abraham and maybe he stills sees the potential is there, so I won’t write the scenario off completely.
