How so?
He was mostly solid. In fact, on his debut at Stamford Bridge he was excellent and in the game at Goodison against Chelsea (which started our good run at the end of the season) he was very good too. He'd have stayed in the side had he not got injured on international duty.
He's coming off the back of a very good performance in the Copa America and he now knows the club. He's settled and doesn't have an injury to deal with and will probably get at least 2 games under his belt before the season starts.
Yeh, I wanted us to sign Zouma and we definitely need another CB, but it's not a slate against Mina. We just need three players to offer three different things so need a player with a bit more pace to come in.
But Mina has plenty of good qualities. He made two mistakes that stand out last season - the clearance against Man City (A) and the bad missed header against Millwall. Every other performance was on the whole, solid. In fact, he was involved in a lot less howlers than Zouma was overall (albeit he played less games!).
The main thing last season was fitness. But that wasn't really in his control. Hopefully with a better pre-season under his belt (he didn't have that last season) we don't have to worry about that as much.
