Whether that will yield a signining is anyone's guess but I am cautiously optimistic.

The earliest Haaland would be signed by Madrid is 2023 and I imagine that means Madrid will miss out on him. Barca is making a lot of noise about signing Haaland this summer but I can't see how that will work given their financial state. My guess is he will be wearing the powder blue of Citeh next year.

Probably a few others, but I'm sure that's the main focus.

They are both represented by Raiola (last I knew). I'm sure that's where Mbappe wants to go, which basically leaves PSG or City as the two teams most able to afford him at least in terms of their typical wage structure. And if Haaland is smart, he won't go to PSG.

edit: the more I think about it, the more I think they could pull it off if they offloaded some wages. That's a big 'if', though.

Bale/Isco/a couple other big ones. Imagine sell Hazard to Newcastle.

They can do it, likely from Bale wages alone.
