They can take that chance too as clubs like Southampton, Leicester and Wolves (jinx?) look fairly rubbish so far and have just as much chance as Fulham and Bournemouth of staying up IMO.Its a calculated bet to improve their squad and either stat in PL this season (might be unlikely) or more likely get relegated but with good squad get back again.
Similar bet to Villa not selling Grealish to us for £25m/30m as new owners 'bet' that with Grealish in side they could get out of Championship into PL (worth say £150m versus selling Greaish for 25m). They got that bet right, got back into PL giving Grealish PL pedigree and persuaded ManCity to vastly over pay for Grealish.
Will Notts Forest also luck it out and win their bet ? No idea but odds don't look too bad ?
