"We had a risky approach, but that was necessary at this stage of the season to get the victory and the team responded well, especially Ronaldo," he said at the final whistle.
"Napoli's first goal came because we were unbalanced, the second was Kakha Kaladze's error for the penalty.
"This was a system we had never really tried before, especially with these particular players, but we will certainly continue honing and using it. They proved they can combine brilliantly on the field and get some great results."
Pato had his Serie A debut and was on target, but so was Kaka and Ronaldo bagged a brace with all three in the Brazilian trident hitting the back of the net.
"Pato has pace, the ability to turn and shoot. We could see that in training as well, so now we have to work on how to provide him with better service. He certainly has the talent.
"Ronaldo only started training on January 2 after basically six months out injured. There's nothing else to say - he is a phenomenon and proved that even when not 100 per cent fit.
"I am happy for him, as he has suffered more than anyone in this season with so many injuries."
The other goal was scored by Clarence Seedorf, who was pushed further back into midfield to make way for the new arrival.
"I would always like to see Seedorf play with this spirit and he was probably Man of the Match for me. He was involved in every move and we all have to be very alert to make the most of this system.
"Seedorf feels he is a Trequartista and played a crucial role in winning the Champions League last year. He is not the only one who must make a sacrifice for the team, but everyone has to work together for the squad."
