Harry, an eight-year-old boy from England who was born with spina bifida, was welcomed to the Estadio Wanda Metropolitano over the weekend.
After a tweet of Harry working hard during a therapy session while wearing an Atleti kit went viral, the Spanish club organised for him to visit for the Barcelona game.
He had a great time as he got to meet players like Joao Felix and Kieran Trippier, who gifted him his shirt, and also assistant coach Mono Burgos.
The club created a video of his experience and shared it on social media.
