The Stamford Bridge boss said his attempts to lure the Manchester United striker to London are over, but believes new forward Samuel Eto'o will bring experience to the side.
The Blues' bid to buy the unsettled England striker has been one of the summer's longest-running transfer sagas, but the deal appeared to be over after Rooney publicly thanked the United fans for a warm reception while playing against Mourinho's men at Old Trafford on Monday.
While the Chelsea coach has failed in his attempts to lure David Moyes' player to Stamford Bridge, he says Eto'o -- who he worked with previously at Inter -- will give his forward line some much-needed experience.
"No, no. For all parties, finished," he told Sky Sports after Chelsea lost the UEFA Super Cup to Bayern Munich 5-4 on penalties Friday. "One thing is to tell you through other people that you want, you want, you want, you want, you want, you want very much, but in the end of the day ... it's the end [of our business].
"We have a good group and Samuel [Eto'o] will give us other kind of qualities in attack -- an experienced player in a team that needs some experienced players."
Mourinho insists he is not disappointed with Rooney's decision not to hand in a transfer request at United, suggesting the player has to do what he feels is right for his career and his life.
"No, I feel it's all right," he continued. "Everyone has to show his life, his future, so for me, I respect that a lot."
