#3 Ederson (Manchester City)
No one could have imagined the impact Ederson would have at Manchester City.
Guardiola, who is known to be particular about his goalkeepers (as with every position on the pitch to be honest), singled out the Brazilian to take over as the No.1 last summer as his Claudio Bravo experiment didn't quite work out the way he wanted.
With a hefty fee of €40m making him the second most expensive goalkeeper in history behind a certain Gianluigi Buffon, Guardiola clearly believed in the former Benfica man.
He has repaid the faith in full, featuring in every single game in the league and playing every minute - barring the game against Liverpool, when a boot to the face from Sadio Mane meant he had to be taken off after 45 minutes.
More than just a shot-stopper, his long goal kicks are a great asset and have been the initiator of many an attack.
City's high backline means that he doesn't have to make too many saves per game, but he has been more than up to the challenge whenever called upon, making several crucial saves over the course of the season.
He has been instrumental in ensuring that City has conceded the joint-fewest goals in the Premier League (20).
Ederson is also very good with the ball at his feet and has a stellar pass success percentage of 84.9% - the highest among goalkeepers in Europe.
Ter Stegen is second with 80.6%; Courtois is second in the PL with 71.2%.
With City marching on towards the league title and also being one of the favourites in the Champions League, we can safely say that Ederson has had an extremely successful debut season with the Citizens so far.
