LONDON (AP) – After winning the Europa League with Porto last season, Andre Villas-Boas makes the step up to the continent's biggest stage when his new team Chelsea launches its Champions League campaign against Bayer Leverkusen on Tuesday.
In taking the job at Stamford Bridge this summer, Villas-Boas acknowledged that bringing European success to Chelsea was high up on billionaire Russian owner Roman Abramovich's wishlist.
The closest Chelsea has come to lifting the Champions League for the first time was in 2008, when the team lost to Manchester United on penalties in the final in Moscow.
Villas-Boas says ''of course it's a dream to everybody, but it's the most difficult trophy to win.''
