Tennis star Eugenie Bouchard owes a fan a date after the New England Patriots pulled off the biggest comeback in Super Bowl history yesterday.

The world number 47 confidently declared on Twitter that the Atlanta Falcons were the champions after they surged to a 28-3 lead in the third quarter of yesterday's Super Bowl.

A Twitter follower quickly replied "If Patriots win we go on a date?" to which the Canadian tennis ace agreed.

Fast-forward a couple of hours later and the Patriots pulled of the miracle to beat the Falcons 34-28 in overtime.
