Oasis frontman Liam Gallagher has long held a reputation for being one of the feistiest characters in the music business – never afraid to speak his mind and never backing down from a confrontation.

Manchester City boss Pep Guardiola, however, got a rare glimpse of what the “Wonderwall” singer is like behind closed doors, and it’s a far cry from the hard-nosed reputation.

Guardiola attended Oasis’ homecoming gig at Heaton Park earlier this year – the band’s first show on home turf since 2009 – with his daughter Maria. There, he not only soaked in the atmosphere and sang along to the hits, he also got the chance to meet the Gallagher brothers, both well-known Manchester City supporters, and their families.

Though familiar with Noel Gallagher, who often attends games at the Etihad, it was Guardiola’s first time meeting Liam, and he’s now opened up about the experience.

“It’s the first time I knew Liam,” he said (via The Mirror). “Noel I’ve been with many times but Liam I never met before and I met him before the concert and he was so kind.”

On the gig itself, Guardiola couldn’t have been more complimentary, describing Oasis as “the best rock band in the last 50 years” while taking the opportunity to compare them to his own City side.

“I don’t know how many countries they sold out but that means how good they have been,” he said. “When (people) say this team will be one of the best, I always say, ‘Ask me after 25 years’. Then if people still talk about that team, it was a good team.”

He added: “It’s like Oasis, no? They come back again and sold out all around the world, it is because they are good. Otherwise, it’s not sold out.”

Even the biggest rock legends have a softer side, it seems.
