Chelsea are into the Champions League semis thanks to Ba's goal.
"I am happy for Demba, he's a good guy, a good pro and a good group man," said Mourinho, "and the fact I brought him on before Torres made him feel he doesn't have 'No.3 striker' on this back.
"His enthusiasm was fantastic and he gave problems to PSG they don't normally have in the French League. His goal means a lot for him and for the club."
