His club record fee of £62m had many 'experts' sceptical about De Bruyne's potential impact, having made very few appearances for Chelsea, this valuation came off the back of just one superb Bundesliga season.
Breaking the Bundesliga most assists in a season record with 21, it was evident to see why City were willing to pay the huge sum. In De Bruyne, City found themselves a midfielder who would remain as their centre piece for years to come, a perfect number 10 providing City with 15 goals and 14 assists in all competitions last season despite have a two month lay off through a damaged knee ligament.
So with the arrival of Pep Guardiola, De Bruyne is keen to be in the best physical condition for the new season putting in extra hours of work on holiday despite having participated in this summers European Championships.
Fitness was never an issue for De Bruyne as last season with the Belgian remaining in fine form till a ligament injury in the Capital One Cup ruled him out for two months, affecting City's performances greatly.
De Bruyne relishing new season
Speaking with Sky Sports De Bruyne remains very optimistic about Guardiola's arrival; "I'm working now quickly on my fitness to come back as fast as I can but there's already a few changes and I'm looking forward to how he's going to manage a team and change some things tactically".
Perhaps this season we may see the best of De Bruyne yet, a manager with fresh ideas and a highly motivated side crammed with talent can only help De Bruyne improve even further on his already impressive stay at Manchester City. The additions of Nolito, Leroy Sané and Ilkay Gundogan will also illeviate the pressure De Bruyne may have felt last season with such reliance being put on him.
