Why? Elliot has done well as the number 2 this season, and has been impressive on occasions, he's still young (for a goalkeeper anyway) and up and coming as well.
Not good enough to be number 2 imho. He's done alright compared to my low expectations of him, but I wouldn't want to rely on him too much. Especially considering Krul seems to be picking up a lot of niggly injuries keeping him out for weeks at a time lately, and I don't believe we have a youngster currently good enough waiting in the wings.
