Any English keeper gets overhyped. Courtois openly mocked him for being a flappy midget at the world cup. England's no. 1 means very little. His main competitors are / were Butland and the Burnley keeper. He's not top class and I can't imagine any of the European giants will be forming an orderly queue soon. He is, however, better than our other recent options (Joel). But ultimately maybe not as good as Howard, who was much maligned too. Maybe on a par, open to opinion.
Frankly, he's right for where we are. Not that bad, not that good. Meh.
