Cristiano Ronaldo’s Champions League debut for Juventus lasted less than a half hour as he was shown a straight red card in his side’s 2-0 win at Valencia.
The Portuguese superstar was involved in a collision with Valencia defender Jeison Murillo, and referee Felix Brych consulted with the assistant official beside the goal before giving the competition’s all-time record goalscorer his marching orders.
But the Old Lady, who had totally dominated until Ronaldo’s dismissal, were awarded two penalties within six minutes either side of half-time, and Miralem Pjanic confidently dispatched them both.
The Italian champions defended well thereafter to keep the hosts at arm’s length, although Juve goalkeeper Wojciech Szczesny did save a Daniel Parejo spot-kick in the final minute of injury-time.
Manchester United top the early Group H table, though, after continuing their recent upturn in form by brushing aside Young Boys 3-0 in Bern to notch a third straight win in all competitions.
Jose Mourinho’s men were inspired by Paul Pogba on the artificial turf, as the French World Cup winner drilled home a brilliant opener before converting a penalty on the stroke of half-time, and setting up Anthony Martial for the third.
It was a different tale for English champions Manchester City who were beaten 2-1 by French side Lyon at the Etihad Stadium after an error-strewn display.
With Pep Guardiola watching from the stands after a touchline ban, City suffered a nightmare first half against an enterprising Lyon, with Maxwel Cornet sweeping in after a mistake by Fabian Delph, and Nabil Fekir drilling home before half-time.
The introduction of Sergio Aguero as a substitute revitalised City after the break, and Bernardo Silva turned in Leroy Sane’s cutback with 23 minutes still to play.
But Lyon, who have only won two of their first five Ligue 1 matches this term, held on to clinch a famous victory and ease the pressure on coach Bruno Genesio.
Elsewhere in Group F, Brazilian youngster Maycon came off the bench to rescue Shakhtar Donetsk a 2-2 draw in their game against group-stage debutants Hoffenheim in Kharkiv.
Holders Real Madrid showed that they are still serious contenders on the biggest stage despite seeing Ronaldo leave for Juventus in the close-season, as Julen Lopetegui’s men saw off Roma 3-0 at the Santiago Bernabeu.
Isco curled home a sumptuous 45th-minute free-kick to give the 13-time champions the lead, before further strikes from Gareth Bale and Mariano Diaz, making his second debut for Real after rejoining from Lyon last month, sealed the victory.
Five-time champions Bayern Munich got their Group E campaign off to a solid start with a 2-0 triumph against Benfica in Lisbon, with Robert Lewandowski and Renato Sanches scoring the goals, while Ajax earlier cruised to a 3-0 victory over AEK Athens in Amsterdam.
