I'd rather they didn't get Pochettino. His stock has fallen on these shores but he'd be decent for United. They've got technically very good players and Pochettino will make them work very hard. PSG are not a side built in Pochettino's image; he's hamstrung by the fact they have the laziest front 3 in history and there's nothing he can do about it. At United it'd only be Ronaldo to worry about and he can work around him.
I'm hopeful they can get Rodgers on board or offer Zidane enough money to change his mind, of the decent options that are available.
