Nah, he's not gonna stay. We need better. I wish he stayed, as an assistant, or maybe even the next gen, but he deserves more, so we can only thank him and wish him the best.
I am convinced that with Motta at least one of Roma/Lazio/Bologna would have been a defeat, and at least one of Genoa/Lecce/Udinese/Monza/Venezia would have been a draw. Enough to miss out on CL. We can say that Igor saved our season.
