Storylines for Matchday 6

1. Now or never for Manchester United
The Champions League's most chaotic team this season has one last chance to save their campaign, but they will need help -- Manchester United have to beat Bayern Munich but hope Copenhagen and Galatasaray draw. Even before they ask others for a favor, they will have to overcome their own demons first.

United traded an encouraging 2-1 win over Chelsea on Wednesday for an underwhelming 3-0 loss to Bournemouth on Saturday that once again showcased their leaky defense. Erik ten Hag's back line continues to be an issue, especially in the Champions League. They have conceded 14 goals in five games, some courtesy of errors from goalkeeper Andre Onana, and will need to stay defensively strong against a Bayern Munich team that boasts plenty of firepower up top.

2. Group F's death knell
The so-called group of death will finally have its haves and have nots by the end of Wednesday, though the picture cleared up a bit on Matchday 5 when Borussia Dortmund booked their ticket to the knockouts. They host a Paris Saint-Germain team who are on the inside track to join them but have been suspect at times in attack despite having Kylian Mbappe on their books.

Newcastle United, meanwhile, take on AC Milan in a game in which both sides need a win and for Dortmund to beat PSG. Neither are in strong form heading into this one -- the Magpies have lost two in a row in Premier League play and conceded seven goals during that time, while Milan lost 3-2 to Atalanta in Serie A action and went down to 10 men late.

3. Must-win matches
Copenhagen's clash with Galatasaray and Newcaslte's meeting with Milan are just two of four matchups on Matchday 6 that are essentially faceoffs between two teams that are battling for one knockout berth.

Napoli's match with Braga on Tuesday and Porto's game with Shakhtar Donetsk have the same feel. Braga need a win to overtake Napoli, who have won once since Walter Mazzari took over for Rudi Garcia. Porto, meanwhile, are level on points with Shakhtar and have the tiebreak, but the Ukrainian side have been solid throughout the group stage and showed they can be giant slayers after beating Barcelona on Matchday 4.
