Wayne Rooney Signs Autograph for NFL Legend Warren Sapp, Who Is Very Excited

On the night Manchester United beat Liverpool 3-1 in the International Champions Cup in Miami, Wayne Rooney was signing autographs.

In one fantastic moment, the striker signs a ball for NFL Hall of Famer Warren Sapp, seemingly unaware of who he is.

Sapp clearly knows who Rooney is, though—his reaction to getting the signature is something else.
