My initial expectation is that it'll be harder to 'sell' us to Nagelsmann than to Slot.
And I don't think we need a manager who doesn't very quickly view us as the right move for him as well as us seeing him as the right candidate.
Of course, Nagelsmann may well see our situation as one that IS right for him, having just been burned by a huge club with politics and big names attached.
De Zerbi may be open to a quick move and might not yet have huge feelings of loyalty to Brighton but will likely be very expensive - the revelation that Chelsea had to cough up over £20 million to take Potter and his team is a fairly strong indicator that we would need to fork over significant wedge to get his replacement out of there.
Potter had extended his contract (he was on a 5 year when we looked at him, IIRC) and upped his pay. De Zerbi is on £1.5M/yr with a 4 year deal, so won't be really expensive.
