Willian has insisted that Chelsea will face Paris Saint-Germain full of confidence after seeing their domestic form improve in recent weeks.
The Blues have looked far more stable under experienced boss Guus Hiddink, who was brought in to replace Jose Mourinho in December.
A run of 12 matches without defeat since the Portuguese was ousted has left Chelsea looking up in the Premier League, but they will now turn their attention towards a midweek European tie with PSG.
Speaking to Chelsea TV on the back of Saturday evening's 5-1 win over Newcastle United at Stamford Bridge, Willian said: "We killed them in 20 minutes and then it was more and more easy to play.
"Now we have more confidence to go [to Paris] and to play. They have a great team, great players, but we go there to try to win the game."
Chelsea were dumped out of the Champions League by the Parisians 12 months ago at the round-of-16 stage.
