Aston Villa striker Ollie Watkins have been incredible this season and is regarded as one of the best strikers in the English Premier League at the moment so I understand why the management Manchester United are trying as much as they can to lure him to Old Trafford this summer. I think it'll definitely not be an easy decision for Aston Villa to let go of their best player at the moment. There's still a possibility that Watkins might leave the club but for that to happen, Manchester United will pay a huge sum of money.
With the way of how the team play, I don't think Watkins is a good option to revive the attacking line, or even Watkins shouldn't be an option at all. He doesn't suit transitional attacks with long through-ball passes. Moreover, Aston Villa won't let him go after achieving the top four finish that will guarantee them playing Champions League next season.
