At least Giovinco might be a little useful on the left in a 4-3-3, Matri was crap playing behind Vucinic & Gio/Quag, what about behind them and Tevez & Llorente? You talk about Matri as if it's a perfect world where he will show his best like in early 2011-12 where he started every game. This is clearly not the case and he will only get worse with even less playing time. Honestly, if he stays and plays even less I'll be surprised if he scores more than like 5-6 goals the whole season. Quag is a far more valuable supersub.
