What happened: Manchester City manager Pep Guardiola made a viral show of support for West Ham ahead of their critical clash with league leaders Arsenal. Leaving his Sunday press conference, Guardiola crossed his arms in the iconic 'Irons' gesture and shouted the club's rallying cry to reporters.

Why it matters: The gesture comes as Guardiola seeks a West Ham upset to swing the Premier League title race back in City's favor. With Arsenal holding a slim two-point lead and only three matches remaining, any points dropped by the Gunners would put City in control of the title race.

What to watch: Arsenal faces West Ham at the London Stadium at 4:30 PM BST today, a match with massive implications for both the title and relegation.
