Luis Jimenez admits Inter Milan's 2-2 draw with Siena has hurt the players.
"The team was really fired up and wanted to win, which you could see by how much we created. Sadly they had two shots and scored two goals.
"Nonetheless, we are still top of the table and are a great team. Now it's time for us to show that," Jimenez continued.
"The Materazzi penalty? He's disappointed - that's normal when you miss a spot-kick, especially one that can win you the title. But we still have a game to play and we will fight to the end."
