I've been a big fan of vucinic, I think the way he links the mid is so important, but recently he has been so shit and so lazy. Conte shouldnt start him when hes like this. Vuci should realise if he doesnt work hard he wont get a starting spot.
Giovinco and Vucinic are fine players individually, but it's as clear as day they don't link up well upfront. No surprise given they are both support strikers, and usually take up the same sort of positions on the pitch, and make the same runs.
