Pep Guardiola called Mikel Arteta for 'advice about certain tactics and strategic setups' when he was playing at Arsenal

The Manchester City manager would call Arteta for advice about certain tactics and strategic set-ups.

He specifically rang him ahead of his side's Champions League clash against Chelsea back in 2012.

An extract from 'Pep’s City: The Making of a Superteam' highlights the working relationship between Guardiola and Arteta.

The book, written by Lu Martín and Pol Ballus, reads: "Arteta and Guardiola always kept in touch, and Arteta lived in the same neighbourhood as Pep's brother, Pere, when he was based in London.

"When Barca drew Chelsea in the Champions League (in 2012), Pep picked up the phone to pick his old friend's brain about their upcoming opponent.

"Impressed by Arteta's critical analysis, Pep made a mental note to seek his advice more often."

Of course, Guardiola hired Arteta as his assistant at Man City, before the 40-year-old left his role at the Etihad to take charge of the Gunners.

"Mikel [Arteta] knows everything," he said. "He’s so good. It’s not because he’s my friend. I know how he lives, I know what he plans, I know how he works. He’s so clever.

"I learn a lot from watching his teams and today I learned something that I can use in the future. He knows everything about football."
