Watch Watford Goalkeeper Ben Foster Give 12-Year-Old Leukemia Patient The Best Day Ever

You might want to have tissues at the ready for this heart-warming video.

In December, Ben Foster made a promise to 12-year-old Molly Hall that he was going to have her be one of the kid mascots for Watford when it hosted Liverpool. He kept that promise.

Molly has leukemia and gets around in a wheel chair, but that wasn’t going to stop Foster and Molly from coming out of the tunnel before kickoff. They even had a little joke about leaving tire marks on the pitch.

Make sure spare tissues are nearby for this amazing video showing the side of football we all simply love.

After Watford’s shocking 3-0 victory against the previously undefeated Liverpool, Foster exchanged jerseys with Reds' goalkeeper Alisson Becker. That night Foster tweeted out he is auctioning off arguably the best goalkeeper in the world's jersey to raise money for leukemia.

Foster truly is one of the nicest and most pure guys in all of football. 

Days after the match, Molly was interviewed on BBC Breakfast where she said the moment was “one of the best days ever.”

Sometimes the most beautiful moments of this game are seen off the pitch, rather than on it.
