Why are Manchester City playing Barcelona at the Nou Camp?

Pep Guardiola's side beat West Ham 2-0 away from home in their opening match of the campaign before thrashing Bournemouth 4-0 at the Etihad on Saturday.

Barcelona announced the fixture at a press conference in June, attending by former Barca manager Guardiola and current club president Joan Laporta.

They were joined by the club's former goalkeeper and coach, Juan Carlos Unzue, who was diagnosed with amyotrophic lateral sclerosis (ALS) two years ago.

All proceeds from the match are set to go to Fundacion Luzon, an ALS research charity.

"This is an honour for us," Guardiola said at the time.

"We want to thank Barca for inviting us to this wonderful venue. We will tell our players why this matters so much.

"It is admirable, and Unzue's words show that. I am very happy to come. By doing this, Barcelona has once again shown why we are the best."

While the reasons behind the unusual fixture are undoubtedly honourable, the decision to stage it three weeks into the new Premier League season – and just three days before the club's next home game against Crystal Palace - has raised a few eyebrows among supporters.

"Why is Man City playing a friendly after the PL season starts?," wrote one fan on Twitter.

Despite the charity match's close proximity to the Palace game, Guardiola has suggested he will field a strong team in Catalonia.

"We're going to bring all the big guns, don't worry," Guardiola insisted at the press conference in June.

The match will kick-off at 2030 (BST) and is available to watch through Manchester City's CITY+.
