he did, but he didn't do it by adopting a Pulis-esque method, he started our passing game from the off. And it took quite a long time to start getting points on the board. It worked in League 1 but its not working in the prem (unsurprisingly)
I don't think Gus is built to manage a team in relegation difficulty, his style isn't to scrap and scrape every point, its far more designed for a promotion-chasing team / top-half team in the prem. Its getting the opportunity that will be difficult for him, but it wouldn't exactly surprise me...
