Juan Mata has described Chelsea's Champions League second-leg encounter with Napoli as "a final" and has said he is hopeful of progression.
The Blues were beaten 3-1 in Naples last month and many have declared the tie over, but the Spaniard believes that his team can overcome the deficit.
He said: "In football, nothing is impossible. At Stamford Bridge, this Champions League, we had good results in the group.
"It's a final for us and I think we can do it. From the first minute, we have to try to create chances.
"We know [Napoli] have very, very good strikers. We have to be careful with them but we are going to press them from the first minute."
Napoli have won their last six games in all competitions, including a 6-3 victory over Cagliari.
