He could be a candidate his teams are very well coached but he works on a small budget so there's only so much he can reasonably be expected to achieve with a club like Brentford.
I don't think he's quite ready for this sort of jump up.
Utd need a coach who's experienced at managing a team in European competitions they need to understand how to coach and prepare for 2 games a week.
I don't think there's actually a list at this point anyway I'm pretty convinced they'll be starting next season with ETH.
