No he isn't ffs. He made a mistake but then he's been out for ages, it's no surprise he was rusty.
And it was a lack of awareness of his man, not his skill in the air that led to the Ings goal. As we've already seen with Clark, time on the pitch is the only answer there.
I said it with Clark and I'll say it again with Baker, it's too early to write him off now. Personally with Okore, these three lads are a big part of our future. It's who we get to play around them now that is key.
Baker's already a good enough CB - he's just rusty as hell.
