The creative midfielder hasn't featured for the newly-crowned English champions since the second leg of their Champions League semi-final with Paris Saint-Germain, but Guardiola confirmed that the Belgium international has returned to training recently and is feeling good.
When questioned on the importance of having De Bruyne return to the team ahead of the Champions League final with Chelsea, Guardiola gave a typically diplomatic response.
"Kev is important like everyone is. The fact when we are able to stick together and be able to push each other will be possible to win it," he said, via the Manchester Evening News.
"Kevin is important like everyone is important. We will see his level for the next games.
"We will have six days after Everton to prepare for the final and we'll think about it then.
"We can't prepare well if we aren't prepared for Brighton and Everton. Tomorrow we are going to play a game to win again, it’s the best way to arrive for the final. Final five or six games will be more focused for Chelsea."
Despite the squad's incredible strength in depth, City are still a far better side with De Bruyne in it and that's evidenced by the fact he's contributed directly to 172 goals in 260 appearances since returning to the Premier League.
The reigning PFA Player of the Year recently signed a new contract at the Etihad Stadium which will keep him at the club until 2025. Having now won three league titles and six domestic cups with the Cityzens, the club's first European Cup would be the icing on the cake.
