Let him continue by all means... but really, he hasn't been tested at all. Not at all.
i've said many times I don't like small keepers, so I don't like Bunn. Is replacing him a priority now, I'm not sure.
He's too much of a heavyweight to run up and down the flank. You could see he was saving himself the whole match. I think this is one of the things why Bacuna played in front of him. Together they are a very strong force on the right.
