Diego Milito insists that his Inter side are now just focused on tomorrow's game against Schalke following the 3-0 derby defeat to Milan.
The Nerazzurri return to action at San Siro on Tuesday when they face the Bundesliga outfit in the first leg of their Champions League quarter-final.
"We want to play a great game tomorrow and win," said the Argentine striker. "We'll look to be protagonists, as always, especially after a loss.
"The squad has a great desire to put in a great performance. However, we don't have to prove anything to anyone.
"The atmosphere is good within the camp, we really want to do well in the tie and reach the next stage. Desire and serenity is what is taking us forward."
Inter were blessed with what looks like a favourable draw on paper, but the South American insists that their German opponents shouldn't be undervalued.
"Schalke are a strong side," he added. "We respect them and they'll be difficult to face. You don't get to the last eight of the Champions League by chance."
Milito has been declared fit for the game after recent injury problems, but he's hoping to make a contribution to the cause.
"It has been a difficult year for me," said last term's super striker. "I've had many injuries to deal with, but there are two months left for me to transform my anger into positive energy.
"However, it doesn't matter if I score or not. The important thing is that Inter reach the Final of the Champions League at Wembley."
