Paris Saint-Germain pair Neymar and Edison Cavani put their differences aside to inspire an emphatic 3-0 win over Bayern Munich in Champions League Group B on Wednesday night
The pair had been criticised by coach Unai Emery this week following an on-field bust-up over a penalty in the 2-0 Ligue 1 win over Lyon but both found the net along with Dani Alves.
Also in Group B Celtic, hammered 5-0 at home by PSG earlier this month, staged a spectacular recovery as goals from Leigh Griffiths, Patrick Roberts and Scott Sinclair gave them a 3-0 win over Anderlecht in Belgium.
Romelu Lukaku scored twice as Manchester United continued their impressive start in Group A with a 4-1 win over CSKA Moscow in Russia.
Meanwhile Basel took advantage of Andre Almeida's 62nd-minute sending-off to hammer beleaguered Benfica 5-0 in Switzerland.
Michy Batshuayi scored a dramatic injury-time winner as Chelsea fought back from behind to beat Atletico Madrid 2-1 in Group C.
Kostas Manolas and Edin Dzeko scored early goals for Roma to see off Qarabag 2-1 in Baku despite a much-improved performance from the hosts who reduced the deficit through Pedro Enrique's first-half strike.
In Group D Barcelona needed a 49th-minute own goal from Sebastian Coates to edge past Sporting Lisbon in Portugal for a win which maintained their 100 per cent start in the group.
Rivals Juventus were also forced to work hard before late goals from Gonzalo Higuain and Mario Mandzukic gave them a 2-0 win over Olympiakos in Turin.
The latest set of results mean four out of the five English teams won their games this week, with only Liverpool being held to a draw.
Here are five talking points from the latest round of Champions League action.
1. Man United show their versatility
By David McDonnell
Once again Mourinho showed his great ability to adapt to the particular demands of different opponents, switching to a 3-4-3 formation to nullify the threat of CSKA and take command of the game from the start.
The formation saw United push up with Ashley Young and Daley Blind playing ostensibly as wingers, with few defensive duties to fulfil because of United's pressure on CSKA, the 68 per cent possession stat at half-time testimony to the dominance of the visitors.
2. Conte's clever in-game management
By Rik Sharma
Chelsea were on top and creating several dangerous opportunities against a struggling Atletico before Diego Simeone decided something had to change.
The Argentine coach had lined up with a 4-4-2 but, seeing his side overrun in central midfield, tinkered and switched to a 4-3-3.
That pushed Angel Correa wide right and Yannick Carrasco wide left, looking to get in behind Chelsea’s advanced full-backs, and allowed Saul and Koke to try and shut down Hazard, who had been a constant thorn in the hosts’ side.
Atletico reaped almost instant dividends when Griezmann opened the scoring and Saul fired wide when he should have grabbed the second before half-time.
It led to a more even game, but Chelsea’s Antonio Conte responded to changing Fabregas’ position on the field to suit the team’s needs.
When Chelsea were chasing a goal he utilised the Spaniard as a quarter-back, behind Bakayoko and Kante, having started with the former as the deepest lying player.
Then, having got what he sought, he swapped them back, to keep the side tough for Atletico to break down.
3. Coutinho back on song
By Liam Prenderville
Plenty of us wondered how Philippe Coutinho would react to his proposed move to Barcelona falling through.
Would he sulk or would he knuckle down.
In the last two games, it has certainly been a case of the latter.
He was excellent against Leicester and notched his second goal in as many games to level the scores in Moscow.
With him in the team, Liverpool are just that bit more classy.
4. Kane hits his stride in Europe
By Joe Mewis
Harry Kane's first-half opener made it four Champions League games in a row in which he has scored.
The only other English player to achieve that is Steven Gerrard and Kane is quickly becoming as important to his side as Gerrard was to his.
And it was another superb strike from the England man, composed as you like as he latched onto Alderweireld's pass and coolly slotted home.
It came at the perfect time - shortly before the break, with his side looking nervy against a very negative side.
That goal changed the game, but his quality shone through on his other two goals, as he netted a perfect hat-trick before leaving to standing ovation with 15 minutes left.
5. Fernandinho binding City's midfield
By David Anderson
Fernandinho is City’s unsung hero, sacrificing himself for the team. He has the quality to play higher up the pitch, but happily plays the holding role to give the likes of de Bruyne and Silva licence to get forward.
He did it again and he shielded his defence, making a goal-saving tackle on Fred when City were under the cosh in the first half.
He was outstanding and gave City’s attacking talent the platform they needed with Shakhtar looking so impressive to make the breakthrough.
6. Iniesta wasted out wide
By Alex Smith
Ernesto Valverde was forced to watch Neymar walk away and then his replacement Ousmane Dembele limp off on his first league start.
The Barca boss's most recent answer? Floating in an unspecified diamond role.
That led to Iniesta being pushed wider and wider as the game went up - as the wing backs failed to bomb forward as expected.
The result was one half of the greatest midfield partnerships of a generation but wasted his evening drifting onto the left flank and lost his impact.
7. Insatiable Ronaldo hits 400
By James Tighe
Eight years and now 400 games since switching Manchester for Madrid, Ronaldo refuses to let age get the better of him.
So routine is his record-breaking that sometimes the significance of his numbers are lost, but 411 goals in 400 games is a barbarity.
Ronaldo is closing in on scoring 100 more Madrid goals than Raul! A legend no one considered could by bypassed and who played 741 games.
8. Star trio live up to their billing
Neymar, Cavani and in particular Mbappe turned on the style as Unai Emery's side served warning that they mean business in the Champions League this season.
Neymar set up Dani Alves for the opener after just 90 seconds and scored PSG's third after Cavani had crashed home a brilliant second goal before half-time.
Mbappe was the architect behind both the second and third goals and looked a threat every time he was on the ball.
9. Bruised Bayern get tactics wrong
Bayern coach Carlo Ancelotti left both Arjen Robben and Franck Ribery out of his starting line-up for his side's second Group B match and questions will be asked of the Italian's decision after a comprehensive defeat.
The Germans, who enjoyed plenty of possession at Parc des Princes, lacked their usual clinical efficiency. But whether either offensive player would have made a difference against PSG's rapier counter-attacks is debatable.
Neymar, Cavani and man-of-the-match Mbappe were irresistible. The German champions never recovered after being stunned by Alves' early opener as PSG's star trio turned on the style at the Parc des Princes.
10. Celtic bounce back
Brendan Rodgers' side were humiliated in the opening week of the Champions League group stages. The Scottish champions took the full force of PSG's expensively assembled attacking line, losing 5-0 at home.
Two weeks later, though, and they have boucned back.
There will have undoubtedly been nerves as they travelled to Belgium but a 3-0 win over Anderlecht shows there has been no lasting damage.
