I would have felt better if Muric was backup instead of Grimshaw to be honest.
He seems a really nice lad, and usually a good keeper, but he has got a habit of having absolute howlers in the big pressure games. FA Youth Cup 2015/16 he had a nightmare, UEFA Youth league semi-final last year he had a shocker and gifted them 2 goals.
Lets hope Mrs. Ederson doesn't give birth on a weekend or CL night.
