Oscar, Ramires and Willian were part of Luiz Felipe Scolari's squad that slumped to that embarrassing 7-1 loss to the eventual world champions Germany.
But Mourinho does not fear for his Samba stars, and has revealed he felt some of his Brazilian's had one eye on the World Cup during the closing stages of last season.
"I was more worried last season. Last season I felt them too much connected with the World Cup and we were January February and March and I was feeling them already there and that really worried me, it as a difficult situation.
"Now it was a big disappointment but you have to move on from that in football. I'm waiting for them and I don't think it will be a problem.
"I have to try to use it in a positive way - you didn't succeed so this season is important for you, lets change the image and the feelings and go back to what you are as what you were in the World Cup was your twin brother."
