Champions League football returns on Tuesday evening with two London clubs in action.
Chelsea, who face Maccabi Tel-Aviv, will look to book their spot in the last 16 with favourable results in Group G, while Arsenal must win at home against Dinamo Zagreb if they have any chance to make the second round.
Bayern host Olympiacos in Munich with either side looking for at least one point to guarantee their place in the knockout phases, while already-qualified Barcelona can secure top spot in Group E with a point from their home match against Roma.
In other games, Porto host Dynamo Kyiv and Gent travel to France to face Lyon.
