bet365 make Maurizio Sarri's side 10/11 (1.91) favourites to win the competition having drawn 1-1 in Frankfurt.
While the Blues were unable to find a winning goal in Germany, home advantage for next week's second leg means the bookmakers believe they're in a strong position.
Frankfurt took an early lead but are 11/2 (6.50) outsiders to claim victory in London on Thursday. The Bundesliga side have some notable wins on their travels this season though, coming out on top against Marseille, Lazio and Inter, so Adi Hutter's men will retain plenty of hope heading to London.
Arsenal have a 3-1 advantage over Valencia in their semi-final clash. A late Pierre-Emerick Aubameyang goal added the gloss to Alexandre Lacazette's double and the Gunners are now just 15/8 (2.88) chances to be crowned champions in Baku with the Spanish side available at 7/1 (8.0) with bet365.
Arsenal's dismal away record this season will be a concern but the Premier League outfit have progressed from 37 of their 40 knockout ties in European competition when winning the first leg.
bet365 now make an all-English final just 11/20 (1.55). This selection is available by doubling the "To Qualify" prices on both sides as there is no specific market available for naming the finalists.
