Goal Australia's betting expert Paul Gough examines the fallout from the opening matchday of the Champions League group stage, with the odds on the Blues and BVB lengthening
Chelsea, the 2012 winners, and Borussia Dortmund, last season's runners-up, are the big easers in betting to win this season's Champions League after suffering shock defeats on matchday one this week.
The Blues went down 2-1 at home against Swiss side Basel while Dortmund suffered a 2-1 loss away from home to much-improved Italian side Napoli, who along with Arsenal, were the big firmers in overall betting following the completion of the opening round of group matches.
Defending champions Bayern Munich remain steady as the $4.50 favourites at bet365 to become the first club since AC Milan in 1990 to successfully defend the world's premier club competition title.
Bayern began their campaign with a comfortable 3-0 win over Russian side CSKA Moscow on Tuesday night.
However Barcelona, champions in 2006, 2009 and 2011, firmed from $5.50 into $5 after thrashing Ajax 4-0 - with Lionel Messi - scoring a hat-trick.
Fellow Spanish side Real Madrid, searching for their first Champions League trophy since 2002, remained steady as the $6 third favourites despite humiliating Turkish side Galatasaray 6-1 in their opening game with Cristiano Ronaldo scoring a hat-trick.
That puts the Blues on the equal fifth line of betting with fellow English clubs Manchester United and Manchester City, who stayed steady at $15 to win the Champions League at bet365 after expected first-up wins against Bayer Leverkusen and Victoria Plzen respectively.
The big-spending Italian club firmed from $51 into $23 and clearly look the best outsiders in this season's competition now that are being led by a manager proven on the European stage in former Liverpool and Chelsea boss Rafael Benitez, while they have one of the best strikers in the world at their disposal in Argentina's Gonzalo Higuain.
The other top outsiders in this year's competition - Atletico Madrid - also firmed in betting from $41 to $26 after scoring a 3-1 win over Zenit on match day one as they showed they are more than capable of making the step up to the Champions League after winning the Europa League in two of the past four seasons.
