Less than 24 hours after FIFA president Gianni Infantino had lauded the United States for "welcoming the world, Capdevila, a member of Spain's 2010 FIFA World Cup-winning team, said his application was rejected because he played in an exhibition match featuring LaLiga stars in Iran in 2016.

The 48-year-old tagged Trump in a social media post seeking help.

"They just told me that I can't travel to the final with my kids because my ESTA (Electronic System for Travel Authorization) has been denied," Capdevila wrote in a social media post.

ESTA approval is required for visa-free travel to the United States.

"Can anyone help me with this? You have no idea how excited I was to be there with all my 2010 team-mates and this team to cheer them on.

"I can't believe they're not letting me into the USA ... and that I'll miss a moment like this with my kids who love soccer so much."

Capdevila also tagged Spain's sports ministry in the post and appealed to United States Secretary of State Marco Rubio for assistance.
