The Czech Republic wing-back said: "We will fight to the end on Sunday against Juventus. We want to win the Scudetto.
"However, if we go into Christmas nine points down on the leadership it will be difficult."
Jankulovski added: "If I could choose one player to remove from Juve it would be (Alessandro) Del Piero. He's a champion and can make the difference.
"But Pavel Nedved is also dangerous. Every year he says he's going to retire, but still manages to play on."
