There’s been plenty of action around the UEFA Champions League today, and it’s only just halftime.

Arsenal is down 2-1 to Greek side Olympiacos, as a brutal mistake from David Ospina has the Gunners in a hole. Olympiacos took the lead around the half-hour mark, but Arsenal got a quick response as Theo Walcott equalized just minutes later. However, a huge mistake from David Ospina would put the Gunners behind once again. The goalkeeper, who got the start in place of Petr Cech, was caught off his line on a corner kick and dropped the cross into his own net, giving the Greeks a halftime lead.

Robert Lewandowski just won’t stop scoring for Bayern Munich, as the big striker tallied twice in the first half to help his side jump out to a 4-0 lead over Dinamo Zagreb. After scoring five times against Wolfsburg last week, Lewandowski has now scored nine goals in his last three games.

Chelsea fell behind at Porto after Yacini Brahimi put the hosts ahead, but Willian tallied just before the break to level things at one.

In Spain, Barcelona is trailing Bayer Leverkusen 1-0, as life without Lionel Messi has gotten off to a rough start for the Catalans.

Perhaps the most shocking scoreline is over in Belarus, as BATE leads Roma 3-0 after 45 minutes.
