"This was certainly not a friendly. It was in the Champions League and PSV still had some chance of qualifying," said Mancini, who saw Julio Cruz hit the only goal of the game.
"The trident went pretty well, as they moved around, helped each other and created chances. Obviously it can improve with time."
This match allowed long-term injury cases like Marco Materazzi and Crespo to regain their fitness.
"Materazzi was able to stay on the field for 90 minutes. After 70 he got a little tired, but he grit his teeth and did well," explained Mancini.
"Crespo also needs to play. He has games sometimes where nothing seems to be going his way, but then when he breaks that deadlock you can't stop him."
