I don't think Mane will be going anywhere. If he'd been anywhere close to his form last season then he'd be out the door on day one of the window for £50m. As it is, he won't get a big enough offer for the club to accept - hopefully.
Not sure about Victor. He's an immense player when on form but a liability when he's not, and I can't imagine three red cards in a season will have helped his price tag much. I'd say he's 50/50 to leave, though I can still see Spurs coming in for him.
I think Juanmi and Martina will be off.
