Nuno had run his course at Wolves and the last season in particular was some of the worst football I've ever watched. Reminiscent of the "Wolverhampton one-one draws" era under Hoddle. Slow, boring, low scoring, defensive, turgid shite. Not only was it dreadful to sit through as a Wolves fan but other fans were openly mocking how boring we were and were praying for us to go down so they didn't have to suffer it too.
But....... That doesn't mean he wasn't a brilliant manager and gave the best football I've ever seen at Wolves before that though, with the best players to ever grace the Molineux turf. And he rightfully goes down as one of the best and most successful managers the club has ever had. Plus he was a great bloke and a real gent it seems. Covid definitely affected him badly and the restrictions it had on him seeing his family. He just seemed to retreat into himself during that time.
But his time was definitely up at that point in that last season. That said I'd have no problem with him coming back here and managing Wolves again. Doubt that would happen under Shi though given what's been posted above.
