I guess Chelsea will be the favorite tonight. Chelsea has the great chance to complete the collection of European trophies today. After cup winners cup in 1971 and 1998 and champions league in the last year, the Europa league is the only competition which Chelsea didn't win so far. The team can close up to Bayern, Juventus, Barcelona and Ajax which are the only teams which won all three competitions in history - so far. Chelsea can make history tonight.
