20:00 CET - With just one hour until kick-off in tonight's late matches, the team news is in across some big matches.
Firstly, from the standout encounter of the evening, as Chelsea host Barcelona, Enzo Maresca has named Estevao and Alejandro Garnacho in his starting lineup ahead of Joao Pedro and Liam Delap.
Which of Estevao, Garnacho and Pedro Neto will play false nine remains to be seen but it is another interesting tactical tweak from the very flexible Maresca.
As for Barcelona, Hansi Flick has left Marcus Rashford and Raphinha on the bench, with both returning from injury.
Over in Manchester and Pep Guardiola has rung the changes as Man City host Bayer Leverkusen, with Nico the only player starting who started against Newcastle last weekend.
19:32 CET - The half-time whistle has gone in both early kick-offs, and that Dahl goal for Benfica remains the only one from the two early games in a cagey start to matchday four.
