Actually, he kept two clean sheets, Burnley and Hull. And he wasn't at fault for either penalty against Sunderland, so what gives?! Yes one big cock-up against Stoke and he should have done better with the second Spurs goal (which ultimately was the defence's fault more than his anyway), but he has pulled off some quality saves too. It's not like Forster didn't receive the odd bit of criticism now and again. You didn't want him to be dropped.
If we have to pick on someone, then why not pick on Fonte for kung-fu kicking an opposition striker in the face? Or maybe big Vic for his below par performance and for the number of yellows he picks up?
To suggest that we should should be playing Gazzaniga, who let's face it, was absolutely woeful when given a chance, is just ridiculous. There is still a lot at stake. Gazza has plenty of time in the future to get the experience he needs.
