Barcelona boast La Liga's top two scorers in Lionel Messi and Luis Suarez, but both players have struggled to replicate their domestic goalscoring in the Champions League.
Messi has netted just four times in seven appearances, while Suarez has started all seven matches for the Blaugrana and failed to find the back of the net.
The Blues, meanwhile, will be hoping that their joint-top scorer in the competition Willian performs as well as he did in the first leg - when he hit the woodwork before scoring an excellent goal.
Messi the value pick
Hazard to strike?
Chelsea know that they have to score at the Camp Nou to have any chance of progressing, and even one goal may not be enough against a Barca side that has 59 goals in just 20 home matches this season.
Willian is priced at a healthy looking 4/1 (5.00) to add to his tally of three Champions League goals this term, while Eden Hazard has also netted three times in the competition and is offered at 3/1 (4.00) to score at anytime.
Prices correct at time of writing. Please gamble responsibly.
