UEFA Champions League: Your Running Commentary

It's around the fourth matchday of the UEFA Champions League that things start to really take shape atop group tables and those with ground to make up feel the pressure even more as their European hopes start to tick away. That's where plenty of teams stand entering Tuesday's critical matches.

AC Milan kicks off the day against upstart BATE Borisov, looking to set the pace atop Group H before Barcelona takes to the field a couple of hours later against the other group minnow, Viktoria Plzen. Zenit St. Petersburg and Shakhtar Donetsk also play in an early match as both look to jockey for position in the unpredictable Group G.

Elsewhere, Chelsea and Bayer Leverkusen can cement places in the knockout stage should both record victories on Tuesday, and Arsenal and Marseille lock horns again just two weeks after a thrilling affair that resulted in a late winner for the Gunners.
