New York City get coaching tips from Sesame Street's Grover: 'Kick the ball with your feet!'

New York City FC welcomed a very special guest down to Yankee Stadium for their MLS game against DC United on Sunday -- Sesame Street favourite Grover.

Not long after the children's TV staple marked its 50th anniversary, he was in attendance to watch the big game.

Grover's big afternoon kicked off with a classic selfie under which the little blue guy revealed he was looking forward to a goal-laden thriller.
