What happened: Manchester City manager Pep Guardiola punctuated his Sunday press conference with a viral show of support for West Ham United. Guardiola crossed his arms in the traditional 'Hammers' salute and shouted 'Come on you Irons!' as he exited the room.

Why it matters: The gesture highlights the razor-thin margin in the Premier League title race, where Arsenal currently leads City by two points with three games to play. A West Ham victory or draw would hand the advantage back to Guardiola and his squad.

What to watch: Arsenal faces West Ham in a critical match that could decide the championship if the Gunners stumble.
