I don't have a Villain in my team (Watkins too expensive for my taste).
He's my biggest worry right now, and he's probably going to drop in price before the next 2 matches I believe, but with Everton, Sunderland, Fulham and Burnley in their next 4 games, keeping him is no brainer, even if ends up not paying off, it will also give me the needed time to evaluate which player would be my no. 1 FW choice, so I think I'm keeping Watkins for the time being, except of course Unai Emery decides to bench or start him from the bench for one of the coming matches.
