Right, so what can you expect to find on today's football news page?

Well, as promised we will look in more detail at Tuesday's key matches, including all the reaction.

We will also highlight the teams who have qualified or have one foot in the last 16 and what all the British sides need to do to make it through.

And for those interested in how the knockout stages might pan out, we will also try to explain how the draw will work.

It's pretty complicated, so bear with us.

The current Champions League table [click the link for the top half and bottom half] is imbalanced due to half the teams playing seven games and the other half playing six, but, in addition to where they are, it is worth keeping an eye on who clubs might play.

Manchester City have dropped a place but their potential play-off opponents has changed from either AC Milan or Atletico Madrid to French pair Brest or Monaco.

Uefa believed the new system would encourage clubs to try and finish in the top two slots to avoid each other until the final. That is looking like Liverpool and Barcelona at the moment.

I don't think anyone has factored in City or defending champions Real Madrid - who are 22nd - performing quite as badly as they have.

Here is the bottom half of the Champions League table.

Teams that finish from ninth to 24th will face an extra play-off round in the knockout phase, while 25th or lower will be eliminated.

Manchester City are 24th with two matches to play.

They head to Paris St-Germain tonight, with PSG down in 26th place and desperately in need of a win...

Here is a look at the top half of the table.

Wednesday's games will complete the penultimate round of matches in the new extended league phase.

Remember, the top eight go directly through to the last 16...

Liverpool set the Champions League benchmark at Anfield on Tuesday night with a 2-1 victory over French side Lille that sealed their place in the competition's last 16.

Arne Slot's side managed that with a game to spare and will go through as league phase winners if they avoid defeat at PSV next week.

Aston Villa, meanwhile, have work to do after losing 1-0 at Monaco.

They remain in the final qualification place for the last 16, but could slip down the table following tonight's results, meaning Villa would face an extra play-off round in the knockout phase if they cannot haul themselves back into the top eight.

Unai Emery's side host Celtic in their final match of the league phase.

Stick with us for all the reaction to Tuesday night's games, as well as build-up to Wednesday's matches.
