To early to judge him in my opinion...However, he does have the potential to be one of our greats if he continues to develop.
Not quite the same level as these, my personal choices: Sorensen Mignolet Gordon (when fit and playing well)
Monty Sorensen Mignolet ...are the top 3 for me. All outstanding keepers. Gordon (could have been amazing) and Mannone (can still be amazing) to make up the top 5. No mentions for Kelvin Davis yet?!
