NFL Hall of Famer Warren Sapp reacted like a little kid when Wayne Rooney signed his ball

There was a brilliant moment after Manchester United beat Liverpool in the final of the International Champions Cup on Monday night in Miami.

Warren Sapp, the NFL Hall of Famer, was pitchside after United claimed their first trophy of the season, and the 41-year-old American sports legend turned to Wayne Rooney to get him to sign his football.

Comically, after Rooney had finished signing his name, Sapp turned towards to rolling TV cameras to uncontrollably react like a little kid who had just met his sports hero.
