Vicario booed by OWN fans after howler | Frank hits back!

Goalkeeper Guglielmo Vicario was reportedly booed by his own club's fans following a significant error, known as a 'howler.' Manager Mauricio Pochettino (implied by 'Frank' potentially being a nickname or misidentification for the manager at the time, or perhaps a separate figure 'Frank' reacting) has publicly defended the player.
