Just seen the highlights. Regardless of what the ‘laws’ may be, my common sense view is that that is not a penalty. It bloody well hurts if you get a ball smashed into your face from close range. In fact, it can break your nose. Kev's reaction was one that any normally constituted human being would make. And his arms were very close to his body (face). By the way, I also believe that the shot is going wide, if you look closely. If anything, Kev's arms deflect the ball back on goal, albeit they do slow it down a lot. The penalty call on the Leicester player is the correct one. His arm is far away from his body.
The highlights didn't show the clean-out of Kelechi, though. As I understood it, we were very lucky indeed to escape without a red on Ed for that one. Even the GMR commentators said as much.
