Everyone's favourite underdogs from La Liga are being backed in to take control of their tie against the Premier League powerhouse, presenting plenty of options for punters
Diego Simeone's team, who accounted for Barcelona in the quarter-finals, are paying $1.90 at bet365 to win at their Estadio Vicente Calderon home, where the visitors are priced at $4.20 and the draw is worth $3.25.
You can get Atleti to reach the final at $1.80, with Chelsea paying $2.00 to progress to the decider against either Real Madrid or Bayern Munich.
The last time the Blues and Los Rojiblancos met was in the UEFA Super Cup in September 2012, a game Atleti won 4-1 thanks to a hat-trick from Radamel Falcao.
You can get $41.00 on a repeat of that scoreline in the hosts' favour this week.
Given both Simeone and Jose Mourinho's preference for keeping it tight, a 1-0 Atleti win or a 0-0 draw appear more likely, and are paying $5.50 and $7.00 respectively.
A 1-0 Chelsea win or a 1-1 draw are worth $9.00 and $6.50 respectively and could also be worth a look.
If you think the home side will have to wait until the second half to get ahead, you can get a reasonable $4.50 on a half-time draw and full-time Atleti win.
