With Madrid having seemingly wrapped up La Liga, and the Catalans having suffered a first-leg defeat to the Blues last week, anything other than a victory this evening would see Barca fail to be crowned either champions of Spain or Europe for the first time under Pep Guardiola.
But despite their "mini slump", the holders remain short-priced, odds-on favourites to win this evening with Paddy Power pricing them at 2/7 (1.29).
Chelsea meantime are on an unbeaten run of nine matches, and are available at 9/2 (5.50) to claim the draw that would see them through to the final and 9/1 (10.00) to record a memorable victory.
Despite their two seismic defeats in a week, Barcelona remain a monumental force at Camp Nou, with Saturday's loss to Real Madrid being their first home defeat in 55 games. With 65 goals in their 17 home matches in La Liga this season, Barca have been rampant in front of goal and that is reflected in the price of 1/2 (1.50) for over 2.5 goals in the match.
But while Guardiola's men have been scoring at home, they have also been conceding. Having gone the entire first half of the season without letting a team score at the Camp Nou in the league, Barca have conceded in six of their eight league matches they have played in their own backyward since the turn of the year.
That makes the price of 5/6 (1.80) extremely tempting and even more appealing when you consider that Chelsea have found the net in their last seven away matches in the Champions League.
If the argument for both teams to score is compelling then bolder punters may well be tempted to invest in goals for both sides in the first half, on offer at a generous 7/2 (4.50), especially considering Chelsea have opened the scoring in each of their Champions League matches.
There is also a Money Back Special on this game from Paddy Power. If Lionel Messi scores the first goal in this game, Paddy Power will refund all losing First Goalscorer, Last Goalscorer, Correct Score & Scorecast singles on the match.
