The 22-year-old playmaker has been one of the Blues’ top performers this term, scoring eight goals and making five assists in the Premier League.
It’s been a fantastic evolution for him, the next phase is to play Champions League knockout phase
And Mourinho has been pleasantly surprised by the midfielder’s attitude since taking over at Stamford Bridge in the summer.
“He’s progressing in everything,” said Mourinho. “He was known as one of the worst trainers; he’s now become, not one of the best, but a good professional in training.
“He was known as having lots of quality, which he’s kept, but not being very productive, and at the same time he didn’t have that defensive culture, of knowing how to defend as a team.
“He now works very hard for the team, he uses his initiative in the game and he’s not a player who does a fantastic action and then disappears from the game for 30 minutes. He’s now trying all the time to be influential in our game.
“He has the responsibility of being a top player so knows he has to be there for his team in every match. Even at Derby, he was on the bench, he came on for the last 30 minutes and immediately you could feel he was on the pitch, so this is the kind of player we want.
“It’s been a fantastic evolution for him, the next phase is to play Champions League knockout phase, which brings a lot of pressure on him because it’s knockout.
“Also he will have the experience of playing at the World Cup, which will be fantastic for him.”
