Manchester United and Newcastle face must-win games to have any hope of reaching the Champions League knockout stages.
The final round of fixtures in the group stages of this season’s European competitions take place this week.
Here, the PA news agency looks at what is at stake for the British clubs involved.
- Champions League
It is crunch time for Manchester United and Newcastle in their bids to reach the knockout stages.
Erik ten Hag’s inconsistent side must beat Harry Kane’s Bayern Munich at Old Trafford on Tuesday and hope the clash between Copenhagen and Galatasaray ends in a draw to leapfrog both and progress from Group A.
Defeat would end United’s European campaign without even the consolation of a Europa League place.
Newcastle, third in Group F, need to beat AC Milan at St James’ Park on Wednesday to have any hope of going through but that will not be enough if second-placed Paris St Germain overcome Borussia Dortmund.
Having already qualified as winners of their groups, the pressure is off for Arsenal and Manchester City as they travel to PSV Eindhoven and Red Star Belgrade respectively.
Winless Celtic are condemned to last place in Group E and sign off by hosting a Feyenoord side certain to finish third.
- Europa League
Rangers travel to Group C leaders Real Betis with qualification on the line.
Victory would seal it for Philippe Clement’s side but anything less would open the door for Sparta Prague, who face bottom side Aris Limassol.
West Ham and Brighton are already through but top spots in their respective Groups A and B – which mean avoiding a play-off tie against a team dropping out of the Champions League – are still to be determined.
The Hammers’ clash with Freiburg and Brighton’s meeting with Marseille, both at home, are effectively shootouts for first place.
Liverpool are already guaranteed top place in Group E regardless of their result at Belgian league leaders Union Saint-Gilloise.

Aston Villa have already secured their place in the knockout stages and will win Group E if they avoid defeat at Bosnian side Zrinjski Mostar.
Aberdeen, who are out of contention, end their campaign at home to Eintracht Frankfurt.
