So, in the end we've replaced Ale with Giovinco and Borriello with Bendtner.
We need to see more from Giovinco in our shirt obviously, but I already dare to say we're weaker in the attacking department in comparison to the last season. Borriello and Bendtner are both cack so it doesn't really make a difference (apart from that Marco, while being a poor player, was actually a cool guy and Bendtner is a shithead) and at the same time I don't think Giovnco will have as much an influence on the team as Del Piero had. Yes, he will play more than Ale and score more than him, but he won't replace the winning mentality, he won't be as decisive in the crucial moments, like Ale in the Lazio match. Don't expect him to reach as many goals and assists as in Parma.
In my opinion, the biggest mistake was not renewing Ale's contract and at the same time not signing a player who possess this kind of winning mentality, a leader on the pitch and not necessarily a poacher (on the contrary to the opinion of majority). Jovetic and Cavani are such players and this summer we probably had the last chance to sign one of them. Even if we signed Llorente, it wouldn't make much difference to the current situation, as I expect he would be anonymous in this team (even if scoring here and there).
I hope Conte's mentality will be enough, but sometimes a team needs such a huge player on the pitch, who will decide the result on his own, especially when Conte won't be there on the bench. And even the greatest depth in midfield won't provide that.
