Rodri struck a wonder goal and Erling Haaland set another scoring record as Manchester City beat Bayern Munich 3-0 on Tuesday in their quarterfinal first leg to continue their quest for a first-ever Champions League title.

Haaland, who scored City's third goal of the night in the 76th minute, has 45 goals in all competitions, a single-season record for a Premier League player, moving ahead of Mo Salah and Ruud van Nistelrooy.

Spanish midfielder Rodri put Pep Guardiola's team ahead in the 27th minute, cutting the ball back to beat midfielder Jamal Musiala and curling a blistering long-range shot into the top left corner beyond the outstretched hand of Yann Sommer.

Bernardo Silva scored their second in the 70th minute, heading in a cross from Haaland. The Norwegian got a goal of his own six minutes later, striking from close range.

"I know that this Bayern team is special," said Guardiola, who managed Bayern from 2013 to 2016. "We got a good result, but we need two strong games. Anything can happen at Allianz Arena. I know that because I was at Bayern for three years."

Rodri celebrated with a long knee slide on the rain-soaked turf at the Etihad, while Bayern's new manager Thomas Tuchel threw up his hands in disgust en route to his team's biggest defeat in the Champions League since a 3-0 loss to Paris St Germain in 2017.

"It was very special for me to score my first goal in the Champions League. At that moment we were struggling because they are a great, great team," Rodri told BT Sport.

"Sometimes we understand we cannot have 80 percent possession. They play too. We scored three and could score four but it is a great result."

"This never happens to Bayern Munich but credit to Manchester City, they were brilliant in both boxes," former Bayern player Owen Hargreaves said on BT Sport. "Pep had a game plan and it worked beautifully."

Meanwhile, Inter Milan struck in the second half through Nicolo Barella and Romelu Lukaku for a 2-0 win at Benfica in their Champions League quarterfinal first-leg match on Tuesday, which put them on course for a first last-four appearance since they won the trophy in 2010.

Barella headed home firmly at the back post in the 51st minute, rising unchallenged to get on the end of a superb cross from center-back Alessandro Bastoni, who was storming up the left side and delivered a pin-point ball.

Substitute Lukaku then converted an 82nd minute penalty after video assistant referee (VAR) referred a handball by Benfica skipper Joao Mario for review by English referee Michael Oliver, who gave the spot kick after looking at the video monitor.

"One of the best matches of this season. We deserved to win, we played very well. We have taken the first step, we hope to do everything to advance," Inter Milan's midfielder Henrikh Mkhitaryan told reporters.

Benfica midfielder Chiquinho said: "We knew it was going to be a difficult game, against a quality team. But nothing is lost. We are going to Milan to turn the result around."
