Here's something you rarely see.

During Sunday's Carabao Cup Final between Chelsea and Manchester City, penalties were needed to decide the match no goals were scored in extra time.

Chelsea manager Maurizio Sarri decided to trust the numbers and sub out Kepa Arrizabalaga for fellow keeper Willy Caballero when before the penalty kicks commenced.

When Arrizabalaga noticed he was being forced out of the game, he didn't want any part of it. He signaled at Caballero to not come onto the field, refusing to walk off the pitch. That triggered Sarri, who then threw a full-on tantrum and furiously left for the tunnel.

 Yikes. Somehow, the 24-year-old who's the most expensive goalkeeper in the world, remained in the net against Sarri's orders.

City's Raheem Sterling potted home the game-winner with Arrizabalaga allowing four goals on five shots, demonstrating that you probably listen to your coach.

It's been a forgetful season for Chelsea. After failing to qualify for Champions League, the club was hit with a two transfer window ban that will run until the 2020-21 campaign. Although they sit sixth in the EPL table, there's speculation that Sarri's tenure could be coming to an end. He’s the 13th manager to coach the club since 2007.
