Unai Emery would be my first choice before Conte tbf. But like you said, he’d be mad to take it. He’s rebuilt Villa a couple of times, replaced Watkins very well which was always going to be an ask, 12 goals scored in 3 games in the champions league and currently second in that league and he’s got a European trophy under his belt. If he came to United now, he’d be grey by January and look like death as it comes to all our recent managers.
