These two sides know each other well. They're squaring off for the 13th time in the Champions League, and despite having not met since April 2012, this is still the fifth-most played fixture in the competition.
Chelsea are unbeaten in their previous seven European clashes against the Catalan giants too, albeit five of those have finished all square. Given Barca's impressive form though, Antonio Conte may feel his side need an advantage to take to the Camp Nou if they're to have a good chance of progressing to the quarter finals.
Unbeaten in the group stage, Ernesto Valverde's men have been able to take their impressive La Liga form (Won 19 Drawn 5) into this competition and are once again one of the frontrunners in the outright market, although it's a very open competition with Manchester City leading the way.
Yet to taste defeat domestically either, breaking down a defence that has only conceded 11 times in 24 league matches this term won't be easy for the Premier League side, but an in-form Eden Hazard will surely test the visitors' back-line. Hazard has been unstoppable in the last couple of matches and the Belgian international could be the key to any success for the hosts.
Regardless of which side you're backing, the choice of either 50/1 (51.0) on Chelsea or 25/1 (26.0) on Barcelona are sure to be popular for anyone opening a new Betfair account ahead of a fantastic midweek fixture list.
