Just a case of a ref who's prepared to guess it was a corner but not prepared to guess it was a penalty. For some teams he would have guessed it was a pen and it would be called a brilliant spot. They'd be replaying the angle that shows conclusively that Forster missed the ball and everyone would be happy. As it is he's not really done his job right but he's got away with choosing the lesser of two possible evils. Roll on video technology. As long as Pigmol's not involved.
