Don't you support both Monaco and United? Do you genuinely think anyone in Monaco's current squad can take us up a level? I'm all on the Mbappe hype train but it's hard to think how we'd fit him in, hope we buy some players this summer in positions we actually need rather than just spending cash for the sake of spending it.
Monaco ? Absolutely not, I only have United in my heart and my NT that's all. I just live in France and I'm following every top Leagues.
(Beside I don't really understand the ones that loves two clubs, It's like loving two girls, basically impossible !)
Regarding Monaco's side, I do really think that a lot of them are worth coming to PL.
Top of them Fabinho and Bernardo Silva. They both showed against Spurs and Chitteh (two legs twice) that they're more than good enough to hurt them, so I'd bet with them being top players.
Then of course you've Bakayoko (I've few doubts about him. Last year he was ok, and this year he's very good, but whether he can be a top one, I don't know).
Mbappé is very different. The guy has something, but he would struggle at Manchester because of the type of game we're playing and the Zlatan's presence for sure. He'd been perfect for Guardiola but they've Jesus.
Subasic is also better than half of the keeper of the PL.
And to finish I'd let one more year to Sidibé and Mendy to see what they can do (Sidibé is not that great to me)
