Chelsea captain Cesar Azpilicueta says he is optimistic that his side will emerge victorious in the first leg of their Champions League last-16 tie against Borussia Dortmund.
Both sides are prepared to lock horns today (Wednesday) at the Signal Iduna Park in Germany.
Chelsea who have spent extravagantly to bring in new players to the Bridge are struggling this term.
The Blues are 10th in the Premier League and have been knocked out of the FA Cup as well Carabao Cup competitions.
Their only chance at silverware this season is to win the Champions League which Azpilicueta believes isn't wishful thinking.
"I never arrive at a Champions League game without thinking we can't win it," said the captain who has already lifted the UCL once.
"The reality is we're not in the best form of results lately but it's a new competition and we have to prove it on the pitch.
"Show concentration, focus, everything that requires playing at such a high level.
"I'm not surprised we're not one of the favourites to win the Champions League but the reality is on the pitch and we have to show it."
"It’s up to us to be ready and show we deserve to be in the next round.”
The Blues under Coach Graham Potter have not lost a game in the Champions League this term.
Of the four games with their new manager in the dugout, they have secured 3 wins and 1 draw in the UCL.
Should they manage a win or draw against Dortmund, they will extend their unbeaten run and likely have a good chance of advancing to the next round.
