Borussia Monchengladbach v Manchester City (19:45 GMT)
Anyone else fancy predicting Manchester City's formation? Here's our effort at rearranging 11 names on a teamsheet. Three at the back and plenty of attacking firepower.
Pep Guardiola makes four changes from Saturday's win at Crystal Palace. Yaya Toure, who scored both City goals at Selhurst Park, is unavailable after missing out on a place in their 25-man Champions League squad.
Injured skipper Vincent Kompany, right-back Bacary Sagna and forward Nolito also drop out. In come John Stones, David Silva, Ilkay Gundogan and Jesus Navas. Bold.
Borussia Monchengladbach midfielder Thorgan Hazard - brother of Chelsea's Eden - is "excused from the team tonight for private reasons".
Gladbach XI: Sommer, Christensen, Strobl, Dahoud, Raffael, Stindl, Traore, Wendt, Johnson, Jantschke, Elvedi.
Besiktas 0-3 Benfica
We've all been to games when it's been quieter than usual but Turkish side Besiktas are taking a new stance on the matter tonight.
Interesting idea. Have a watch.

Dortmund pile it on
Just the 12 goals in Borussia Dortmund's win over Legia Warsaw last night. Who wins a game 8-4? Apart from your under-15s team?
More of the same tonight? Come on Ludogorets v Basel - time to shine.
Arsenal v Paris St-Germain (19:45 GMT)
Both sides have already qualified, but whoever wins at the Emirates tonight wraps up top spot in Group A.
Group winners will play group runners-up in the knockout stage, and finishing second has traditionally been Arsenal's downfall...

If you get through to the knockout stage of the Champions League, you would like the easiest game possible so winning the group is important.
Having said that, by definition you still have to play one of the best 16 teams in Europe so it's not going to be easy either way.
Also, a lot can happen between now and the next stages games in February. Your form might dip, you can lose all sorts of players so overall I wouldn't be too bothered.

Arsenal v Paris St-Germain (19:45 GMT)
Arsenal
Four changes from the Arsenal team which drew with Manchester United as goalscorer Olivier Giroud starts.
Also in are Alex Iwobi, Kieran Gibbs and David Ospina.
Besiktas 0-3 Benfica
The other early kick off this evening is between Turkish side Besiktas and Portuguese Champions Benfica in Istanbul.
Benfica are well on top at the break and if they take the three points, they are through regardless of other results.
However, Besiktas need Napoli to lose in order for them to make the last 16.
Sort of irrelevant but check our this goal from the corresponding fixture in the Uefa Youth League from earlier today...
Benfica's 17-year-old Gedson Fernandes chips the keeper from the halfway line... , external
FC Rostov 3-2 Bayern Munich
In one of tonight's early games, Russian side FC Rostov are under 10 minutes away from pulling off a win against Bayern.
Munich are already through.
Celtic v Barcelona (19:45 GMT)
Has Lionel Messi ever been 'piped' into a game before?

Celtic v Barcelona (19:45 GMT)
Two changes for Celtic from Friday's win at Kilmarnock. Emilio Izaguirre and Tom Rogic return.
A couple of names you might recognise return for Barca. The surnames of Suarez and Messi are down on the teamsheet after they missed Saturday's draw against Malaga.
There are eight games in total to keep your eyes across tonight. Here's the big three which will occupy most of our attention:
Borussia Monchengladbach v Manchester City (19:45 GMT)
Celtic v Barcelona (19:45 GMT)
Arsenal v Paris St-Germain (19:45 GMT)
All sorts of possible permutations await but Benfica, Napoli, Besiktas, Barcelona and Manchester City can all book their passage into the last 16 this evening.
Borussia Monchengladbach v Manchester City (19:45 GMT)
Manchester City
Manchester City make four changes from the team which beat Crystal Palace on Saturday. Yaya Toure scored twice but is not registered for the Champions League so drops out.
In come John Stones, David Silva, Ilkay Gundogan and Jesus Navas.
The big 10
We already know 10 of the last 16 in the Champions League. Hats off to Leicester and Arsenal among this lot:
Arsenal, Paris St-Germain, Atletico Madrid, Bayern Munich, Monaco (won group), Bayer Leverkusen, Borussia Dortmund, Real Madrid, Leicester City (won group), Juventus
Borussia Monchengladbach v Manchester City (19:45 GMT)
Defeat in Barcelona last month left Manchester City in a spot of Champions League bother.
They had already been held to a draw by Celtic and four points from three games meant that safe passage to the last 16 was looking anything but assured.
But, after a big win at home to Barca, Pep Guardiola and co are sitting pretty again.
A win in Germany will see them safely into the last 16, joining Leicester and Arsenal.
Glad to be back in Gladbach? We shall see.
