Hughes is a very capable manager.
We’re talking someone who has taken Blackburn from relegation threatened into Europe, reaching three consecutive Cup semi finals in the process. He also signed and created the core of City’s first title winning team - signing the likes of Kompany, Kolo Toure, Lescott, Zabaleta, Bridge, Barry, De Jong, Tevez, Adebayor and Bellamy who would win the title the season after he left.
He qualified for Europe via the league with Fulham too, he kept QPR up which is what he was appointed for and he achieved Stoke’s best league finish in over 40 years.
He took over Southampton with them 1 point above the drop, he kept them up and got them to the FA Cup semi final.
That’s a little over a decade and there’s some great achievements there. Sure, you can look at how his time at Stoke soured toward the end or the few months pre-Christmas at Southampton last season that saw him sacked - like all managers he’s made mistakes.
As I said, he wouldn’t be my 1st choice but I could certainly understand the logic if the board got him in.
