Manchester City have won the Carabao Cup final after defeating Chelsea 4-3 in a penalty shootout.Raheem Sterling scored the winning goal as Pep Guardiola's side won their first competition of the season.But everyone will be talking about the exchange between Kepa Arrizabalaga and Maurizio Sarri just before the shootout got underway.Penalties were approaching when Chelsea goalkeeper Arrizabalaga went down with an injury. He has been troubled by a hamstring problem.Sarri decided to bring Willy Caballero - who saved three penalties in the 2016 EFL Cup final shootout against Liverpool - but Kepa refused to come off.The 24-year-old stood and waved Caballero away, despite Sarri continuously calling for him to come off.The Chelsea boss eventually relented and Kepa remained in goal for the shootout.

Kepa refuses to come off

It was a truly remarkable scene. Caballero, who had stripped off ready to come on, headed down the tunnel when his teammate refused to come off.

Sarri was furious with his goalkeeper and had to be held back from Antonio Rudiger as he vented his frustrations at full-time.

We've never seen anything like it before.

Kepa, who saved Leroy Sane's penalty in the shootout, is surely in trouble for his behaviour now. He undermined his manager and he's unlikely he will be allowed to get away with it.

What had been a rather dull final ended in fireworks.

In the shootout, Eden Hazard scored an audacious penalty to keep Chelsea alive before Sterling netted from 12 yards to hand the trophy to City.

It means their hopes of winning the quadruple remain alive.
