Sleep-deprived Manchester City winger Jack Grealish admits he has had “the best day and night” as the club celebrated their treble-winning season following the capture of the Champions League title.

Even a typical Manchester downpour and passing lightning storm could not dampen spirits as Pep Guardiola and his squad paraded their newly-acquired European Cup alongside the Premier League trophy and FA Cup.

City returned from Istanbul on Sunday afternoon and it has been one long party – with celebrations set to continue for a while longer as Grealish was overheard to ask striker Erling Haaland: ‘Are we having it?’ while on their one-mile tour around the city centre.

Haaland’s response was to empty a bottle of champagne over the £100million signing, who later told a large crowd assembled in St Peter’s Square: “For the past 24 hours I’ve had the best day and night. To be fair I don’t think I’ve had any sleep.”

The players had arrived for their parade via Metrolink tram from the Etihad Stadium but the weather delayed proceedings somewhat.

Supporters had expected to be let into the fanzone in front of the stage at 5pm but due to the threat of lighting storms that was pushed back by 90 minutes.

Rain started falling shortly after 6pm and, as a result, the start of the proceedings was delayed by 40 minutes but it did not deter the fans who came out in their droves to cheer on City’s squad and manager Guardiola, all wearing matching ‘Treble winners’ T-shirts.

Halfway around those now-drenched T-shirts started to be dispensed with as City’s 52-goal striker Haaland threw his into the crowd and, with the rest of the squad, arrived on stage 45 minutes later than expected still topless.

“We had to be the best parade with this rain, otherwise it is not Manchester,” Guardiola said to the delight of the waiting crowd.

“We don’t want sunshine, we want rain, so it was perfect. They (fans) are used to the rain.”
