I think that's probably true. But really, what does he have to lose by coming now? I don't imagine there will be any pressure on him and nobody should be casting too much judgement based on what happens in the next four months. Then he can still bring in his own people at the end of year.
I have to say though, would the Lyon coaches even want to leave? I don't know what the financial situation there is like but somehow I doubt we'd be offering them much better than whatever they're on now. Not only that but they are at a successful club who are in with a real chance of winning the title this year and will almost certainly be in the Champions league next year. I know all that is less important to a coach than to a player but still.
