Thousands of Manchester City fans gathered to celebrate their team’s historic hat-trick as they paraded on an open-top bus through the city.
Blue flares were lit and fans threw inflatable bananas into the air as some players went shirtless in the pouring rain.
Manager Pep Guardiola was seen smoking a cigar as fans climbed the lamppost.
The march was delayed by a thunderstorm. City beat Inter Milan 1-0 in the Champions League final.
This came after the club won the Premier League and FA Cup titles this season.
Guardiola said his team’s Champions League success after Rodri’s 68th-minute goal was “written in the stars”.
Guardiola was then seen lying in bed waving his fist at the crowd as the players showed off the three trophies.
Defender Rubén Dias and striker Erling Haaland were among the many players dressed after getting drenched in the rain.
Haaland, 22, led a troupe of dancers onto the stage just after 20:00 GMT as midfielder Calvin Phillips sang England defender John Stones.
Guardiola praised the fans for coming out of the storm.
He said: “We have to be on our best show with that rain, or it wouldn’t be Manchester.
“We don’t want sunshine, we want rain, so it’s perfect. The fans are used to the rain.”
Captain Ilkay Gundogan said it was “surprising” that they had “three titles”.
England midfielder Jack Grealish said: “Over the last 24 hours I’ve had the best of the day and the night.
“To be fair, I don’t think I slept.”
The team had departed from Tonman Street, Deansgate, slightly late at 19:00 BST due to inclement weather and traveled to St Mary’s Gate.
