It's a little more than that, my observation in a minute, I'm really on the fence on Johnson, he has moments, he finds himself in good positions but .. (and that could be just development time, hopefully)
But watching him yesterday, he's not brave, at 22, he's not willing to go for it, he's not willing to put his body into a 50/50 and that for me is pretty bad thing.
Now maybe he's just settling in, and maybe with the stiches he was a little tentative, but right now he's the obvious first team upgrade when everyone is fit.
