Three young Barcelona fans had quite the experience on Tuesday.
A day before Barcelona takes on Arsenal in the second leg of their Champions League round-of-16 series, the club trained per usual only to have three youngsters run onto the field. Instead of having security usher them out, Barcelona's stars took a different course entirely: They integrated them into training, posed with them for pictures and signed jerseys.
According to Spanish outlet Mundo Deportivo, two 10-year-olds and one 12-year-old skipped school and took advantage of an opening during the part of the session open to media.
