Lazio goalkeeper Fernando Muslera is looking forward to facing Napoli striker Edinson Cavani at the weekend.
The Uruguayans know each other well from their time together with the national team.
Speaking to La Gazzetta dello Sport, Muslera said: "I know all the Matador's secrets. We often challenged ourselves to a penalty shoot out in training.
"I know where he puts the ball. The problem is that he knows that I know. It would be a great duel.
"His shots have an impressive power. I guarantee you that it hurts a goalkeeper's hands saving his shots.
"Moreover, Edinson has another quality. When he shoots inside the penalty area, 90 per cent he always scores."
