Rafa Benitez's side need to come out all guns blazing to stand a chance of making the final, and Jamie Dickenson is backing the visitors to win the game with Ba scoring firstChelsea travel to Swansea for their Capital One Cup semi-final second-leg knowing they must turn around a 2-0 deficit to stand any chance of making it to Wembley.
Aston Villa were knocked out last night by Bradford City, who are due to face either the Swans or the Blues in the capital on February 24.
Swansea are the 1/3 (1.33) favourites to qualify, with Chelsea priced at 9/4 (3.25) to make the showpiece event, but the better odds to side with are in the full-time result market.
Rafa Benitez's side have been clinical on the road recently, winning their last six domestic away days and scoring a whopping 20 goals in the process.
They have been shaky at home, but seem more comfortable away from Stamford Bridge, and at the price of 17/20 (1.85) Chelsea are well worth backing to win this game in South Wales over the 90 minutes.
For their part Swansea have won just four of 12 home games in the league this term, also recording the most draws on their own patch in the division with six.
A victory at the Liberty Stadium for the hosts is on offer at 10/3 (4.33), while the draw is out at 3/1 (4.0).
With Chelsea forced to attack from the beginning - and with creative midfielders like Juan Mata, Eden Hazard and Oscar set to start behind the prolific Demba Ba - it is hard to imagine the visitors will not be troubling the scoresheet.
The lacklustre Fernando Torres must surely be dropped after toiling to no avail against Arsenal at the weekend, while his new £7 million rival deserves the nod having struck three goals in just three starts.
Ba even scored a legitimate goal against Swansea in the dying minutes of the first leg after coming on as a sub, but it was harshly ruled out for offside.
With Ba ready to step into Torres' shoes and Chelsea set to attack from the first whistle, backing the Senegal international to open the scoring at 7/2 (4.50) offers pretty decent value.
