People judge his time at Arsenal unfairly. He got our dump of a team to the EL final, something even Wenger couldn't do.
They point out his transfers ie Pepe forgetting Pepe was also not his signing, our previous DOF was sacked before he could be in deep trouble when it was being revealed how corrupt the Pepe signing was. When Emery was there our dressing room also downed tools. Aubamayeng, Ozil were very toxic. I am a match going Gooner and I was there in those games where Swansea, Southampton etc made us look mugs at home and to anyone watching it was obvious some of the big players simply were joggling around not giving one feck.
After he was forced out by the dressing room, Arteta came in with Edu and I think at that time it was apparent to the board Ozil first and then Aubamayeng later needed to go. Both were our best players, assists and goals wise but the decision was made to sell them for the betterment of the team. He was heavily criticised for it, even here, but it turned out to be a great decision as the club backed him on this. Emery did not have this luxury nor did he have an Edu like thing. United need to do this and get rid of Bruno and Rashford and other entitled 'stars' who absolutely show no desire or are in no way deserving of a captains armband.
Saying this, I do feel Emery has issues handling toxic characters in the dressing room, PSG is one example, then Arsenal. However I think he was at Arsenal simply at the wrong time and its unfair he's judged on this. I think the club were in denial when Emery was here about our real quality of the team compared to maybe their lofty view. It was only when Emery left did everyone realise how awful our team was and it needed major changes, major decisions and some hard choices. I do feel with good backing he can be a success at a big PL club. At United with a good DOF with him and the club backing him to get rid of your underperforming players, he could be a massive success.
