Sell Schneiderlin 15m, get Felli for free. No-lose situation. He'd be a superb addition for 2/3 years, no doubt about it.
If we could offload Schneiderlin for actual money, then use that for a creative midfielder and also poach Fellaini, our centre-of-the-field options would be smashing: Rooney, Davies, Gueye, Fellaini, creative midfielder, Beningime... all that just for a domestic season of one game per week. In a year's time we offload Rooney and decide if Davies is going to make it or not, and get another passer in and we're looking great.
