He got Nice to their highest finish and Champions league football and also had Balotelli playing arguably the best football of his career.
The thing Favre, he hits a brickwall. He's very good at getting teams overachieving and into European football - which is where largely most of his success has come. He hits a brickwall when it comes to getting teams over the line in terms of winning leagues etc. But, that's not the job we are looking for in the short term, we actually just need Favre to do what he does best, get teams playing good football, develop players and get us moving up the league.
Longer term, obviously he could be an issue, but I don't think he's a long term appointment anyway, he's 62/63 now.
