European football on BT Sport: A jam-packed Matchday 4 awaits across the continent featuring an abundance of huge clashes including Atletico Madrid vs Liverpool
The Champions League, Europa League and Europa Conference League return to BT Sport for another huge week of action.
Another week, another three days of unmissable European football. Matchday 4 is here and with it come a fistful of must-see clashes between the best teams on the continent.
A dramatic Matchday 3 saw Liverpool and Atletico Madrid play out a barnstormer at the Wanda Metropolitano and Cristiano Ronaldo do it yet again for Manchester United as they recovered from two goals down to defeat Atalanta.
With all the fixtures reversed, we’ve rounded up all the big storylines and talking points to whet your appetite ahead of another blockbuster week.
Tuesday 2 November
With no Europa League or Europa Conference League games brought forwards, it's all about Europe's elite club competition with the usual eight games apiece on Tuesday and Wednesday.
Thomas Tuchel's defending European champions dismantled the Swedes at Stamford Bridge with a comfortable 4-0 win and a repeat result would see Chelsea go level on points with Juventus ahead of the Old Lady's clash with Zenit at 8pm.
Salzburg meanwhile were too good for Wolfsburg and the Austrians will fancy their chances of making it back-to-back wins to all-but seal qualification for the last-16.
The later kick-offs features Manchester United's trip to Bergamo with Ole Gunnar Solskjaer in need of not just a win, but a performance too, as he feels the pressure in the Old Trafford hotseat.
The Red Devils came from two goals down to defeat Atalanta at The Theatre Of Dreams a fortnight ago with Ronaldo bagging the winner just as he did against Villarreal.
But given the disastrous result against Liverpool, in which Ronaldo was ineffective, there remains plenty of scrutiny on the Portugal forward as well as his manager.
Another under-pressure boss, Ronald Koeman, is also in action when Barcelona look for just their second win away at Dynamo Kiev, while also in Group E Bayern Munich bid to seal a knockout spot at home to Benfica.
Elsewhere on Tuesday, Sevilla and Lille go again in search of their first win of the competition after a goalless draw in north-west France and Manchester United's group opponents Villarreal and Young Boys do battle in Spain.
Wednesday 3 November
Carlo Ancelotti's Real recovered from the nightmare loss to Sheriff with a win over the Ukrainians in Kiev but still sit below the Moldovans in Group D.
Milan meanwhile are rock-bottom of Group B and in desperate need of points to keep their knockout hopes alive when they take on second-bottom Porto.
After a thriller in Madrid, which saw Mohamed Salah's 78th-minute penalty clinch a 3-2 win, Atletico visit Anfield for the reverse fixture at 8pm.
Los Colchoneros (the Mattress Makers) felt aggrieved when Antoine Griezmann - who had netted twice to peg Liverpool back - was shown a 52nd-minute red card.
Salah's winner then compounded the ever-combustible Diego Simeone's frustration and Liverpool can expect to face a highly-motivated Atletico side on Merseyside.
Pep Guardiola's Manchester City are in action once again against Club Brugge, who they saw off 5-1 in Belgium, as they bid to place one foot in the knockout stages ahead of their clash with PSG.
The Premier League champions have been scoring freely, domestically and on the continent, and viewers can expect another flurry of goals when Brugge visit The Etihad.
Group A's other clash features Paris Saint-Germain in action against RB Leipzig. The Parisiens edged a thriller 3-2 in the French capital thanks to Lionel Messi's double and will hope the Argentine can produce once more on Wednesday night.
In Real's group, Italian champions Inter must follow up their Matchday 3 win over Sheriff with another against the debutants if they are to keep pace with the race for qualification.
And Group C features an intriguing clash between the top two sides as Borussia Dortmund seek revenge for a thrashing at the hands of Ajax and Sporting bid to defeat basement boys Besiktas once again to keep their hopes of a last-16 place alive.
Thursday 4 November
The Europa League and Europa Conference League take centre stage on Thursday with no fewer than 32 European clashes across a packed day of football.
Beginning with two exotic 3.30pm kick-offs in the Europa Conference League- Estonia's Flora against Cyprus' Anorthosis and Kazakhstan's Kairat Almary hosting Azerbaijan's Qarabag - BT Sport will bring you all 64 teams in action across our digital platforms.
The Hammers are in dreamland on their return to European competition, with three wins from three including a thumping 3-0 triumph over the Belgians at the London Stadium on Matchday 3.
Another win over Genk puts David Moyes' men in the knockout stages and given how things have gone so far, Hammers fans will be feeling confident.
Things have been decidedly tougher for Rangers in Group A. The Scottish champions have just one win and sit third heading to Denmark to face bottom side Brondby.
Ahead of clashes with Sparta Prague and Lyon on Matchdays 5 and 6, Thursday's Brondby game might just be a must-win clash for Steven Gerrard's Gers.
Brendan Rodgers' men looked on their way out of the competition midway through the Matchday 3 clash with Spartak in Moscow. The Foxes trailed 2-0 and were set to end the night with just a point from three games played in Group C.
Then, Patson Daka happened. The Zambian exploded into life and netted four times to secure a dramatic 4-3 win and breathe new life into Leicester's hopes of advancing to the knockout stages.
It's been a similar story for Celtic. The Scottish giants lost both opening games before a routine win over pointless Ferencvaros a fortnight ago.
Ange Postecoglou's men will hope for another win over the same opponents, coupled with a favourable result from Germany when Real Betis travel to Bayer Leverkusen.
And in the Europa Conference League there's an important game for Tottenham and under-fire boss Nuno Espirito Santo when they take on Dutch side Vitesse Arnhem in north London.
Santo is under pressure at the Tottenham Hotspur Stadium and can ill-afford a repeat of the disappointing loss to Vitesse in the reverse encounter.
Jose Mourinho, another man with Spurs affiliations, is under similar scrutiny when his AS Roma team host Bodo/Glimt - also at 8pm.
The Italians were trounced by an incredible 6-1 scoreline on Matchday 3 and must show far better when they welcome the Norwegian league-leaders to the Stadio Olimpico.
