Manchester City star Jeremy Doku is thriving as the club's new supersub this season.

The 21-year-old Belgian was hoping to become a starter for Pep Guardiola's team this term.

However, he is still behind Jack Grealish when every player is fit, even though he made positive impacts when he came on against Real Madrid and then Chelsea.

"Jeremy against Madrid was unbelievable," said manager Pep Guardiola to reporters.

"Jeremy has made a step.

"When he arrived, after West Ham, I was like 'Oh my God, unbelievable player' and until his injury he was at a top level. Always when he came from the bench the impact was not good. From the start was good, the bench not good.

"We talked about that, how he has to make an impact when the players are more tired and he has a special quality one against one. He changed the game, the same as Madrid when he created a lot of chances.

"Jeremy is an exceptional player one on one, close to the box. He is young and has to improve many, many things but in the final third he is massively important for us."
