Caceres was ok tonight, you should remember that he has been a bench player for quite a while. He will soon get used to starting matches and do much better.
As stated about Cannavaro earlier this week: replacing a CB is one of the hardest things to do on short order. He did fine.
Definitely taken into consideration. But you still have to judge the performance as such, in isolation.
It's like defending a young lawyer by saying: "Oh well... he's so fresh, he's bound to make a few mistakes." Perhaps, but the courts will still judge him as they would any other experienced lawyer, as soon as he takes on the role. There are no excuses. Niente alibi.
All in all, Caceres did not do well tonight, and he was not by any means "fine". Hopefully, he will improve.
