Portugal Colonial - Arsenal, Real Madrid win Champions League openers, Juve snatch dramatic draw

Tottenham Hotspur also won on the tournament's opening night which saw outsiders Union Saint-Gilloise and Qarabag claim first ever victories in the Champions League proper.

Arsenal are eager to make a big impression again in Europe's elite club competition, following their defeat by eventual champions Paris Saint-Germain in the semi-finals last season.

They got off to an ideal start in the Basque Country, with Gabriel Martinelli and Leandro Trossard scoring late goals to settle the game.

The Brazilian had only just come on when he ran through to open the scoring in the 72nd minute at San Mames. Arsenal then went on to seal the victory late on as Trossard -- another substitute -- scored with the aid of a deflection.

"We started to grow throughout the game. In the second half we were more fluent, dominant, and the finishers made the impact for us to win the game," said Arsenal coach Mikel Arteta.

- Half century for Mbappe -

Real Madrid came from behind to beat Marseille 2-1 at the Santiago Bernabeu, despite playing the closing stages of the game down to 10 men.

Marseille, winners of the inaugural Champions League in 1993, stunned the home crowd by taking the lead through Timothy Weah midway through the first half.

The record 15-time European champions grabbed an equaliser before the interval when Mbappe converted from the spot for the first time after Rodrygo was fouled in the area.

Xabi Alonso's side lost Trent Alexander-Arnold to injury early on and were reduced to 10 men in the second half when his replacement, Dani Carvajal, was sent off following a VAR check for a headbutt on Marseille goalkeeper Geronimo Rulli.

But the home side still snatched all three points thanks to another Mbappe penalty late on after Facundo Medina was harshly penalised for handball.

"For me it's a penalty, but I understand there are people who don't (think so), we're all lost with this rule," Mbappe, who reached 50 goals for the club, told broadcaster Movistar.

Thomas Frank's Spurs, who qualified for the Champions League after winning last season's Europa League, edged Villarreal 1-0 in North London.

The match was decided by a farcical early own goal from Villarreal goalkeeper Luiz Junior, who contrived to let Lucas Bergvall's cross trickle into the net.

The victory maintained Tottenham's impressive form under new boss Frank. "It was a very even game that we just edged," he told broadcaster Amazon Prime.

- Eight-goal thriller -

Juventus against Dortmund in Turin was a repeat of the 1997 final won by the Germans, and the fixture more than lived up to its billing, finishing in a spectacular 4-4 draw.

Remarkably the first half ended goalless, with the breakthrough coming seven minutes after half-time when Karim Adeyemi put the visitors ahead from a fine low strike.

Kenan Yildiz equalised with a stunning effort high into the top corner just after the hour mark, only for Felix Nmecha to put Dortmund back in front in style.

Dusan Vlahovic made it 2-2, but Yan Couto restored the Bundesliga side's advantage and they appeared to have sewn up the points when Ramy Bensebaini converted a penalty in the 86th minute.

However, Vlahovic pulled one back in the 94th minute and then crossed for Lloyd Kelly to head home in the sixth minute of stoppage time, rounding off an extraordinary evening.

There was similar drama in Lisbon, where Benfica seemed to be cruising at home to Qarabag after Enzo Barrenechea and Vangelis Pavlidis scored early goals.

However, Leandro Andrade pulled one back for the club from Azerbaijan before Camilo Duran equalised and Oleksiy Kashchuk turned and fired in from inside the area four minutes from time to make it 3-2.

It is the first time Qarabag have ever won a match in the Champions League proper.

Union Saint-Gilloise qualified after winning a first Belgian title in 90 years and they recorded a 3-1 victory away to PSV Eindhoven.

Promise David, Anouar Ait El Hadj and Kevin Mac Allister scored their goals in the Netherlands before Ruben van Bommel pulled one back.
