The first round of group stage fixtures for the 2016/17 UEFA Champions League season were played on Wednesday night.
In Group C's rescheduled match, Manchester City easily overcame Borussia Monchengladbach 4-0 at the Etihad Stadium.
Sergio Aguero fired home a hat-trick before Kelechi Iheanacho added a late goal to give Pep Guardiola a perfect start in Europe with City.
In Group E, Bayer Leverkusen were held to a 2-2 draw by Russian champions CSKA Moscow despite leading by two goals after 15 minutes.
Swiss striker Admir Mehmedi gave the Germans a 9th-minute lead from a seemingly offside position when controlling a slipped through ball which defected off Hakan Calhanoglu.
Calhanoglu then doubled Leverkusen's lead with a deflected effort from the edge of the area six minutes later.
But CSKA respondedthrough Alan Dzagoev with a fine finish on 36 minutes before pulling level moments later courtesy of Roman Eremenko.
The other group fixture saw Monaco beat Tottenham Hotspur 2-1 in front of a massive 85,000 attendance at Wembley Stadium.
Bernardo Silva and Thomas Lemar had the French visitors two to the good before Toby Alderweireld pulled one back for Spurs who were unable to find another goal despite dominating the second half.
Group F produced a dramatic finish to Real Madrid's eventual 2-1 victory over Sporting Lisbon.
Bruno Cesar's 47th-minute strike had the Portuguese giants heading for a shock upset at the Santiago Bernabeu before former Sporting star Cristiano Ronaldo came up with a stellar free-kick from range prior to Alvaro Morata's headed winner deep into injury-time.
In Poland, it was a procession as Borussia Dortmund hammered Legia Warsaw 6-0 with six different scorers finding the back of the net, including star striker Pierre-Emerick Aubameyang and summer returnee Mario Gotze.
Over in Belgium, Leicester City made their mark on the Champions League by beating Club Brugge 3-0 in their debut thanks to a double from Riyad Mahrez.
In the other Group G match, Danish champs FC Copenhagen held Porto 1-1 in Portugal after Andreas Cornelius cancelled out Otavio's early opener.
And Group H saw Olympique Lyon beat Dinamo Zagreb 3-0 in France while Europa League winners Sevilla held Italian powerhouse Juventus to a 0-0 draw in Turin.
