Francesco Guidolin is without both star strikers for the visit to Napoli, “but Udinese have other weapons in our armoury.”
The Friulani had seemed unstoppable with a 14-match unbeaten run in 2011, but two consecutive defeats to Lecce and Roma have seen them slide out of the top four.
To make matters worse, on Sunday night they travel to Scudetto-chasing Napoli without the injured Antonio Di Natale and Alexis Sanchez.
“We knew that Sanchez wouldn't recover in time, but I thought Totò would make it,” said the Coach.
“He had played last Saturday despite the pain in his ankle, but yesterday he couldn't even walk without feeling it.”
There are reports Guidolin could change the system with German Denis the lone centre-forward against his old club.
“I want to see my team fired up and concentrated, because we are fighting for the Champions League and every game is important.
“We need extra against Napoli, as they are strong and playing in a heated atmosphere. We're going there to play our game.
“It's true the forwards are out of action, but we have other weapons in our armoury and I'm not remotely worried. We need to be aggressive tomorrow against the second best team in Serie A.”
When asked what had happened to suddenly see Udinese lose two on the bounce, Guidolin insisted the bubble had not burst.
“For months we made no mistakes, whereas in the last two games we did. If we climbed the table it's because we didn't do anyone any favours.”
