Kevin De Bruyne has opened up about his decision to leave Jose Mourinho's Chelsea in 2014.

The Belgian ace moved to Stamford Bridge as a youngster in January 2012 but left just 24 months later when Wolfsburg came calling.

De Bruyne, who has since gone on to win the Premier League with Manchester City, only played nine matches for Chelsea and spent the full 2012-13 season on loan at Werder Bremen.

Speaking on new City documentary All or Nothing, De Bruyne said: 'I was only 20 years old when I decided to sign for Chelsea, and I got my chances in the first few games and I thought, okay, things are going well, I play okay, we won the games.

'But then one day it stopped. Knowing me, I had not a lot of patience at the time, I decided to go in January.'

In October 2013, Mourinho publicly criticised De Bruyne after dropping him from the Chelsea squad for a Champions League qualifier against Steaua Bucharest.

Mourinho, who is now in charge at Manchester United, said at the time: 'I try to be honest with Kevin. He's not selected because I didn't like the match he played against Swindon and I didn't like the way he was training.'

City paid Wolfsburg £55million to bring De Bruyne back to England in August 2015 and he linked up with Pep Guardiola when the Spaniard became the club's manager a year later.

In contrast to Mourinho's words, when Guardiola speaks about De Bruyne it is generally in glowing terms.

Guardiola said recently: 'Kevin is a top player, shy — he doesn't talk too much — but on the pitch is completely different.

'He is a competitor, physically so strong. He can do everything - he doesn't feel the pressure.

'Now he is one of our captains and he deserves it because he takes a lot of responsibility on the pitch.'

De Bruyne is set to miss a significant chunk of City's season as they bid to retain their Premier League title. The 27-year-old is facing up to three months out after damaging knee ligaments in training.
