If you didn't see this coming, you can't have been paying attention.

Bayern Munich were bulldozed by a spectacular Manchester City at the Etihad Stadium, a 3-0 dismissal of the 10-in-a-row Bundesliga winners a sign of the times.

It was a bad night for the men in red, a desperate one for Dayot Upamecano; a match to remember for City, and perhaps the moment the doom-mongers had seen coming.

How can this City team be stopped? They were terrific and dominant, save from a 20-minute spell at the start of the second half when Bayern gamely gave just about as good as they got.

A team into which mind-blowing sums have been invested were destined to scale heady heights such as these, though. The wealth of talent at Pep Guardiola's disposal is unsurpassed, the Abu Dhabi ownership having backed the manager to bring together an elite pool of players.

This is why some with a Bayern allegiance would like German football's tight ownership rules to be relaxed. For now, a tight rein on spending means Bayern cannot possibly compete in the transfer market with City.

Twenty-five years ago, City were hurtling towards relegation to England's third tier. Now they surely are everyone's Champions League favourites, ripe to be crowned kings of Europe for the first time with one foot in the semi-finals.

Erling Haaland's 45th goal of the season put the seal on this rout, leaving Bayern facing near-certain elimination in front of their own fans in next Wednesday's second leg.

Rodri's wonder strike had broken the deadlock, and Bernardo Silva hit the second to quell Bayern's brief resurgence.

Norwegian Haaland has managed the most competitive goals by a player for a Premier League club in a single season. And if you didn't see that coming, you can't have been paying attention. Deadly for Borussia Dortmund, Haaland was bound to score bucketloads in this City team.

Bayern, traditionally the club that scoop up the best talent from within the Bundesliga, had been powerless when the chequebooks came out for Haaland.

Haaland fancied this occasion early on and took aim from an outlandish angle, from an opportunity given a miniscule xG rating of 0.028. The wild slash with his left boot soared over the bar.

Jamal Musiala was denied by an outstanding block from Ruben Dias as Bayern carved out the best chance of the opening 25 minutes, but then £62.6million man Rodri rocked the Germans with his sensational finish.

The wickedly swerving strike with his left foot came from 25 yards, as Bayern waited for a pass from the player who had not scored in 43 previous Champions League appearances.

Former City winger Leroy Sane fired 18 inches wide from 30 yards to serve a reminder of Bayern's threat, but shooting from that range hinted at desperation.

By half-time, Rodri had passing accuracy of 90.3 per cent and had won six of his eight duels. He had also won possession on 10 occasions, more than anyone else on the pitch, while losing the ball just four times. Even setting aside the goal, he had been magnificent, and City's defending was terrific, with Ederson yet to make a save.

Sane drew a first save from Ederson in the first minute of the second half, and the Brazilian did not make a clean catch, rather juggling the ball. He made a better stop two minutes later, and again it was Sane with the strike after being played through by Musiala.

City could not take advantage of haphazard Bayern defending as Joshua Kimmich blocked Haaland's thumping shot, but that was a sign of trouble to come for Bayern.

Bayern brought on former Liverpool forward Sadio Mane in the 69th minute, but it was 2-0 seconds later, before Mane got to touch the ball.

Upamecano looked to step out of defence but hopelessly lost the ball to Jack Grealish, whose clever backheel played in Haaland. As Bayern braced for him to shoot, the Norwegian crossed instead and Bernardo Silva planted a powerful header through Yann Sommer's grasp.

Sommer saved from substitute Julian Alvarez as Bayern's defence was ripped open again, and the third goal arrived when World Cup winner Alvarez crossed from the right flank, £50million centre-back John Stones headed across goal from the far post, and Haaland, the most coveted player in Europe last summer, volleyed in calmly from a chance he was never going to miss.

Joao Cancelo, on loan to Bayern from City, was booed onto the pitch when he appeared as a substitute. Bayern don't think they have the funds to buy the City cast-off, which sums up the difference between these outfits.

City have won their last 11 home games against German sides in this competition by a 42-10 aggregate, and Haaland has 11 goals in seven Champions League games for City now.

It was entirely predictable he would get on the scoresheet at the Etihad Stadium, but here's a thing that changed for Haaland in this game: as well as taking his goals tally to six in eight appearances against Bayern, he finished on the winning side.

He had lost all seven games he played for Dortmund against Bayern.

Things change once you join City. This is a winning machine, a team on a nine-game streak now, and nights like this make you fear for Arsenal, sat increasingly precariously at the top of the Premier League. They make you fear the rest of Europe will be powerless to prevent a rhapsody in blue come the Champions League final in Istanbul, too.
