I'm going to add - although Cech doesn't make many obvious errors - I am not feeling confident in him anymore. It's not taking much to get past him these days and I feel he's becoming too indecisive.
We all know how a keeper who isn't sure of himself transmits negative energy to the defence. See Almunia, Fabianski, Sczesney.
It may just be bad form but still I'd give Ospina a run.
I totally agree with you on this, I've been saying this since the summer.
He declining very quickly and his kicking puts us under massive pressure.
