It's matchday four in the Champions League group stages. In other words, things are starting to get serious as some of Europe's elite battle for places in the last 16.
Here's a rundown of tonight's most important clashes.
Chelsea vs Ajax
Lampard's men snatched a late win in Amsterdam to further underline their status as away-day specialists. They've now won five consecutive matches away from home, but clean sheets at Stamford Bridge continue to be few and far between. With Ajax known as counter-attacking specialists, this one could go to the wire again.
Borussia Dortmund vs Inter
Antonio Conte's new-look Inter side is hard to break down at the best of times. These two sides are level on points after three games and trailing runaway leaders Barcelona, making this match a virtual playoff for second place in Group F. Dortmund has drawn four of their last five Bundesliga matches and the goals have dried up for Paco Alcacer and Jadon Sancho. Dortmund drew 0-0 with Barcelona here earlier in the group stages, more of the same could be on the cards tonight.
Barcelona vs Slavia Prague
Messi's men laboured to a 2-1 win away from home in Prague a fortnight ago, but it should be much more straightforward at the Nou Camp tonight. Barcelona is unbeaten at home in the Champions League since September 2013, a formidable record.
