Aston Villa's group stage in pictures
Aston Villa have a great chance of qualifying for the last 16 of the Champions League in their first season in Europe's elite club competition for 41 years.
The likeliest route to a top-eight finish for Villa is that they beat Celtic and Atalanta fail to beat Barcelona away.
Alternatively, Villa would overtake Bayer Leverkusen if they win by two goals more on the night (eg. 3-0 to Villa, 1-0 to Leverkusen).
Here's how it has unfolded so far.
In their first-ever Champions League game, Villa triumphed in Switzerland with a 3-0 win over Young Boys.
Goals from Youri Tielemans, Jacob Ramsey and Amadou Onana ensured Unai Emery's side got off to the perfect start.
Their second game of the campaign was a repeat of Villa's 1982 European Cup final success against Bayern Munich.
Jhon Duran scored nine minutes after coming on and then Emi Martinez produced heroics to save Harry Kane's header in the dying minutes of the game and secure three points.
More success came at Villa Park 20 days later, with Duran on the scoresheet once more as Villa won 2-0 against Bologna.
John McGinn got the other, his free-kick evading everyone to clinch the victory.
The first bump in Villa's campaign came against Club Brugge when Tyrone Mings was penalised in controversial fashion for handball in the penalty area.
The Belgian side scored the spotkick and held on to win 1-0, spoiling Unai Emery's second anniversary at the club.
A 0-0 home draw with Juventus followed before Villa travelled to Germany to face RB Leipzig.
Unai Emery's side went ahead twice through McGinn and Duran only for Leipzig to peg them back each time. However, two minutes after coming off the bench, Ross Barkley scored a deflected winner to win the game 3-2 and take Villa up to third place in the table.
Finally, Villa missed the chance to effectively qualify for the last 16 against Monaco as the French side won 1-0.
However, Villa still approach tonight's game in a very promising position to automatically progress to the knockout stages. Opta's supercomputer gives Emery's side a 52.6% chance of finishing in the top eight, and a 76.8% chance overall of getting through to the last 16.
