TLF - having slept on it (and putting to one side the manner of Guidolin's departure), in some respects I'm probably "happier" the day after Bob's appointment than I was the day after Guidolin's.
For one, I'd heard of Bob & his earlier (International) achievements prior to his appointment - can't say I'd heard of Francesco - and secondly, I'm sure that the Yanks will back Bob financially to (help) retain our PL status. The depreciation in the value of their investment would be colossal if we were to be relegated.
Additionally, many on here (myself included) had concerns over whether Guidolin's tactics, safety-first/negative approach etc would be good enough to save us this season - on that basis, a change of Manager may give us the lift we need.
Whilst, I don't think Bob was the Preferred Candidate of anyone on this Forum (again, myself included), he is now the Manager & he will have my support.
