This left wing saga is horrible. The best options would be Afellay, Vargas and Bastos and it seems Afellay and Bastos are not going to happen and Vargas may not either. Giaccherini looks like a VERY average player. We need class in this department. I am also not convinced about Elia. Maybe we should just try and get Giovinco back - he would cost us very little and he is probably better than Elia.
But honestly, if there are no good options out there for the left wing, then perhaps Marotta needs to tell Conte to consider using different tactics. There may be more options for central mids. Krasic-Matri-Vucinic is good for the front three Vidal-Pirlo need one other good partner because I am not sure that Marchisio and Pazienza are the right players tbh.
But to be honest, Bonucci to Zenit for 8m and picking up both Alex (8-10m) and Lugano (free) is AN ABSOLUTE no brainer. Bonucci had 1 good season with Bari and he is no where good enough to be a starter. If he is a bench player then 8m is a high valuation - SELL HIM. I know he is young but he is not exactly that young - he is 24....if he is not world class now he will never be to be honest.
