Don't want to make this a Nuno thread but they were not bad at all in his first two seasons with two 7th place finishes and a semi-final of FA Cup straight out of the Championship, that's better than Poch did at Southampton and better than Beisla for Leeds (both of those achievements were rightly lorded too). Last season he had major injury issues to his best players Neto (knee), Jiminez (skull), Marcal (can't remember), Bolly and Dendonker missing Xmas period, Podence out for 2 months, Castro Otto (ACL) only played 7 games, Neto (knee) missed 6 months!! All this in one season with a small squad in only it's 3rd season in PL whilst also navigating Europe.
like I said, I've no idea how good he will be or how he'll have us playing (Pre-season FWIW has been encouraging but a pinch of salt and all that). They will be fitter than under the dinosaur and even that I'd expect to translate into a more entertaining game to watch.
