Juan Mata insists Chelsea's home form in Europe this season gives them ample reason to be confident of dumping Napoli out of the UEFA Champions League on Wednesday.
The Blues trail the Italians 3-1 from the opening leg of their last-16 tie, and enter the game on the back of consecutive wins under interim boss Roberto Di Matteo.
Chelsea had a perfect home record in the group stages, netting 10 goals and conceding none, leaving Mata in confident mood ahead of the Stamford Bridge leg.
"In football, nothing is impossible," the 23-year-old said.
"At Stamford Bridge, this Champions League, we had good results in the group - 3-0, 2-0 and 5-0.
"All the supporters, for sure, will be cheering us. It's a final for us and I think we can do it. From the first minute, we have to try to create chances to score.
"We know that they have very, very good strikers. We have to be careful with them but we are going to press them from the first minute."
Since losing the opening leg in Naples, Chelsea have parted company with former manager Andre Villas-Boas, who was sacked following a string of below-par performances.
Mata admits the managerial change has not been easy, but has faith in Di Matteo - who has been handed the reins until the end of the season - following his solid start.
"It wasn't easy, because you know we had a change, a big, big change," said Mata.
"But I believe the team is still believing, is still working very good and the two wins, for sure, bring to us a lot of confidence."
