The Blues manager is delighted to have seen the skilful Belgian voted the club's Player of the Year and is confident that he and the whole team will have a stronger 2014-15
Hailing the Belgian's crowd-pleasing flair and "artist's touch", the Portuguese is looking forward to the 23-year-old doing even better in 2014-15.
"Obviously the fans enjoy and respect people like Gary Cahill, Cesar Azpilicueta, John Terry - people that are so stable during the season and do an incredible job for the team - but people like Eden bring the magic and win matches in one action," said Mourinho on Chelsea's season-review DVD. "They have the flair and the artist's touch of the football.

Mourinho returned to Chelsea for a second stint last summer but was unable to win his third league title at Stamford Bridge, the Blues four points adrift of Manchester City in third.
He is adamant, however, that they will do better in the campaign to come, despite acknowledging: "Next season will be very, very difficult, even more so.
"I know Chelsea will be better but maybe the other teams will be better too so it will again be the kind of league where you don't know if you're going to finish first or finish sixth.
"In this moment I have to think and feel and say we want to finish first."
Mourinho is not getting carried away, though, acknowledging that the club need to rebuild following the exits of veterans Ashley Cole and Frank Lampard.
"I was a little part of the process that made Chelsea a force in the last decade and I come back with the dream to try to be a little part again of the next decade," he continued.
"After 10 years of titles and great moments, this is a moment to rebuild again because teams don't last for ever. Clubs, yes, but not the teams. In the same club you have to build another team. That's what we are doing and, for sure, the results will come."
