You reckon?
Southgate, Allardyce, Hodgson and McClaren are the four most recent English appointments. One failed in his only ever club job and wasn't great with the U21s, one dinosaur twat who should never have got close, one who was great at lower mid-table clubs (still pulling the same trick now) but came horribly unstuck at Liverpool and one who nearly got sacked six months before he landed the England gig.
Potter has never finished higher than 9th in the PL and as I say Howe wouldn't leave Newcastle if they don't sack him.
Keegan is the last big name Englishman, even then it was in the last century and he'd shuffled away to third tier Fulham (where he was obviously punching miles below his weight, just being paid well to do so).
Hoddle got the job despite being rubbish for Chelsea, didn't even finish in the top 10 once.
