There are no clashes between titans during Tuesday's Champions League action, but most of the big sides are facing tricky fixtures loaded with upset potential.
Wednesday features the biggest matchups in the UEFA Champions League -- and Groups A-D having the best matches is probably going to be a trend -- but there's still a lot of very watchable football on Tuesday's slate. All of Manchester United, Bayern Munich, Juventus and Barcelona are up against tough opponents who will feel confident in their abilities to pull off an upset. Chelsea and Arsenal's opponents are likely to be less optimistic.
The day kicks off with an early match in Russia, where Celtic probably shouldn't be much of a match for Spartak Moscow. However, they shouldn't have been able to keep up with Benfica on Matchday 1 either, but they pulled off a credible 0-0 draw. Another draw would keep Celtic in contention for a surprise knockout stage place.
Shakhtar Donetsk go away to Turin as part of the normal slate of games, and their match against Juventus should be the best of the round. Manchester United, whose lack of athleticism in midfield was exposed at the weekend, go away to Cluj. The Romanian side doesn't have much in the way of firepower, but they are coming off a 2-0 win over Braga, and they're certainly decent in the center.
Barcelona should be able to defeat Benfica, but the Blaugrana have a Clasico to look forward to and have required miracle comebacks in their last two La Liga matches. Bayern Munich are in a similar situation away to BATE, where they should be able to win, but BATE were extremely impressive in their 3-1 win over Lille two weeks ago.
