The Champions League returns for its fourth match this week, with a number of interesting fixtures lined up.
After an exciting matchday three where a total of 30 goals were scored, we look forward to a total of 16 matches, spread over two days, this week.
We take a look at some of the key matches to look forward to;
Dortmund v Inter Milan
Antonio Conte's Inter Milan grabbed their first group win last time out against the German side in a 2-0 victory. It will be Borussia's turn to avenge the defeat when they host the Italians on Tuesday night.
Inter Milan are in good shape at home and won their last match 2-1 way to Bologna on Saturday. Borussia, on the other hand, won their match in the Bundesliga, and this will be another exciting match to watch as both sides try to catch up with Barcelona, who are top of the group with seven points.
Chelsea v Ajax
Frank Lampard's men are on a good run currently and will be confident hosting the Dutch side on Tuesday night.
They beat their opponents last time out, breaking their unbeaten run at home in a 1-0 triumph. Chelsea have not won a match in Europe this campaign, losing 1-0 at home to Valencia in the opening match.
It will be a tough match for the two teams, who are favourites to advance to the next round from the group.
Crvena Zvezda vs Tottenham
Mauricio Pochettino's side grabbed an important win last time out in the competition, beating their opponents 5-0 in London.
They have been a bit sloppy at times though, especially playing away from home, and this will be a stern test of character.
They drew 1-1 against Everton on the weekend having lost Son to a redcard following a nasty injury on Andre Gomes.
Can they pick a win that can almost certainly see them qualify behind Bayern Munich?
