'Master and apprentice' - Balague on Guardiola and Arteta

Pep Guardiola and Mikel Arteta's relationship has cut across a range of strands over the years and evolved along with their managerial styles.

The pair go head to head at Etihad Stadium on Sunday in a match many have billed as a Premier League title decider. A win for Guardiola and second-placed Manchester City would cut the lead of Arteta's Arsenal side to just three points, with a game in hand.

The Spaniards' relationship started in 1997 when Arteta joined Barcelona's academy - meeting his idol, Barca skipper and fellow midfielder Guardiola. Their time as team-mates was brief, but a friendship was forged.

Communication between the two managers cooled significantly when Arteta gave up his role as Guardiola's assistant in Manchester back in 2019 to take charge of Arsenal.

While the City boss's other former assistants maintained closer contact, Arteta stepped away - and that distance created silence.

While Arsenal learned to compete at the highest level, Guardiola continued to evolve.

That tension - between adapting and remaining faithful to an idea - defines the 55-year-old's career.

"He starts incorporating new concepts," said Pep Segura, former director of football at Barcelona. "Above all defensive transition, that's where he evolves enormously.

"Arteta incorporated more physical profiles than Pep. Pep seeks more technical players… Arteta looks for strength, speed, power."

But there are still plenty of points of convergence.
