He's only managed in the French League which is so so weak. I have massive doubts over his ability to adapt to managing in the PL. If he was joining a bottom half team then maybe but he's going to have to get us in the top 10 at least, plus get us into the EL knockout stages. If he proves me wrong I'll be happy but surprised. Massive risk Saints. Massive, massive risk.
And Koeman managing in the even weaker Dutch league for 3 seasons and getting sacked pretty much everywhere else he went, wasn't?
