Are we sure that was a deflection? I've watched it over and over and tried to see it hit Baines and I just don't think it did.
That said, I both agree with Paddock and everyone else here. I am fully confident with him in goal, and I doubt any keeper in the world could've gotten to that shot with its movement and pace, but I think he might occasionally concede a goal that's fired at the top netting or near the top corner. Those are concessions I'm willing to make given how good he is at everything else.
