This is Bradley Lowery.
The five year old from County Durham is fighting neuroblastoma, a form cancer that affects nerve tissue. He is fighting the illness for the second time in his short life, and his family was recently told by consultants that there would be no long term cure for him. But he’s keeping up the fight.
Bradley is a fanatical supporter of Sunderland, and the football world has rallied around to support him and his family.
Bradley led the Sunderland team out for their fixture against Everton in September, and Everton also made a £200,000 donation towards a fund for him to receive treatment in the US.
His mother announced that the family has decided on a treatment of oral chemotherapy that will tide Bradley over through Christmas and let them enjoy the holidays together. So now, in order to help Bradley have the most magical Christmas possible, players and fans are asking people to send him Christmas cards.
It’s not just Sunderland fans that are coming out to support him. Supporters of clubs all across the country are getting involved.
Former Liverpool and England striker Robbie Fowler has tweeted about the request, as has Sky Sports presenter David Jones.
It looks like they’ve already got a lot so far.
