Despite Thibaut Courtois' obvious brilliance for Atletico Madrid last season, there were still some who questioned Jose Mourinho's decision to bring him back to Chelsea and replace Petr Cech as the Blues' first-choice goalkeeper. Some felt the 22-year-old was still too inexperienced for the more physical Premier League, but so far he has been an absolute revelation. The Belgium number one has been faultless to date, as Chelsea have been far and away the most impressive side in the Premier League. He has made some top class saves, particularly against Manchester United last weekend, and his dominance from crosses and general reading of the game are world-class. Courtois has the feel of a young Cech about him- the Czech looked similarly unbeatable when he joined Chelsea in 2004- and he is well on his way to becoming the best in the world in his position. It's frightening how young he is, and there is no reason why he can't be first-choice for the next 15 years, presuming he remains at Stamford Bridge during that time.
