The 2015/16 UEFA Champions League group stage kicked off on Tuesday night with Groups A to D in action.
In France, Ligue 1 champions Paris Saint-Germain commenced their campaign with a 2-0 win over Swedish side Malmo courtesy of summer signing Angel Di Maria's first European goal for the Parisian giants who were also served by a second-half Edison Cavani header.
In Spain, Real Madrid were convincing in their 4-0 triumph over Ukraine's Shakhtar Donetsk. Karim Benzema struck first, pouncing on a howler from visiting keeper Andriy Pyatov on the half-hour, before Cristiano Ronaldo helped himself to a second-half hat-trick.
The first two came from the penalty spot before the Portuguese ace completed the treble with a close-range header, to take his Champions League tally to a record 80 goals - three clear of Lionel Messi.
Former PSV hero Memphis Depay had given the visiting Red Devils a 41st-minute lead before Hector Moreno responded on the stroke of half-time and then Luciano Narsingh won it for the home side just before the hour-mark, however, the night was dampened by the double leg fracture sustained by United left-back Luke Shaw.
In Portugal, Benfica needed second-half strikes from Nicolas Gatian and recent arrival Kostas Mitroglou to see off FC Astana 2-0 - Kazakhstan's first side in the group stage of Europe's premier club competition.
Full of hope, Premier League leaders Manchester City went down to Serie A heavyweights Juventus despite drawing first blood. Giorgio Chiellini's own-goal in the 57th minute was cancelled out by Mario Mandzukic's glancing effort from Paul Pogba's delightful ball before Alvaro Morata scored a stunning left-footer in the 81st minute to down the Sky Blues.
Tricky winger Vitolo won two penalties early in the second half, with Kevin Gameiro converting the first but rocketing the second into the woodwork, before Ever Banega slotted home comfortably form 12 yards after Gladbach conceded a remarkable third spot-kick in less than 20 minutes.
Summer arrival Yevhen Konoplyanka then wrapped up it with a stunner in the 84th minute, after only coming on at the corner, beating Yann Sommer from the ensign set-piece with a speculative effort from a ridiculous angle.
Wednesday nights fixtures include Arsenal's trip to Dinamo Zagreb, Chelsea at home against Maccabi Tel Aviv, reigning champions Barcelona away at AS Roma and Bayern Munich paying a visit to Olympiakos.
