All true but the lure for a confident and ambitious manager, as TF is, of a big club is the prospect of big success if you back yourself to overcome the obstacles and take the risk of failure.
TF strikes me as a patient, realistic and thoughtful person. So it may be that the unfinished work here he’s mentioned when asked about other managerial vacancies includes stuff beyond our more prosaic hopes as fans. Or it may be that he sees our ceiling as being already pretty much reached.
Yes, failure after moving is possible. But so is failure after not moving.
If Man U say, here’s £15m a year for three years, here’s £1bn in transfer kitty, here’s a CL campaign and a PL campaign where the aim is to finish much higher than 16th and be looking like a well managed, coached and structured team, it’d be mighty tempting.
