I don't think it's accidental that we haven't bought a centre back as we're saving the pennies in the hope we can get Mbappe. If Mbappe is determined to leave we probably have best chance of getting him outside of Real and Barca.
What's in our favour is the ridiculous additional cost to both Barca and Real in signing him. No doubt with all the PSG Neymar nonsense Real are probably lobbying the Spanish government to ensure Monaco is no longer designated a tax haven.
On the plus side we have to be getting some encouragement as otherwise we would be briefing like hell that we're not keen so...
