The Nigerian and Belgian were sent to Merseyside for the rest of the season, and the Chelsea boss believes the club have made the best decision for the players' futures
Lukaku joined Everton until the end of the season while Moses headed to Liverpool, with the arrivals of Samuel Eto'o and Willian having liimited the scope for first-team football.
And Mourinho believes the Blues have made the best decision for the long-term future of the players.
"I think its time for everyone to stop thinking about selling and buying players," the Blues boss told Chelsea TV.
"There are always little things to do on the last day, people to leave. We have to think about the club but we also have to think about what is best for the players individually.
"We decided Moses and Lukaku - two players we were more than happy to keep - that it’s better for the club and the future of the players if they go on loan.
"With Lukaku, we have Fernando, Eto’o and Demba. Of course he would get playing time, but it’s the choice of playing basically every weekend.
"He had lots of clubs and options, and we have to respect his decision."
