RYAN Reynolds and Rob McElhenney have previewed the 'David vs Goliath' FA Cup fourth round rematch between Wrexham and Sheffield United. 

The Reds visit Bramhall Lane this evening - with the winner earning the right to host Premier League giants, Tottenham Hotspur. 

Ahead of the game, which will see nearly 5,000 Wrexham fans travel to south Yorkshire, the club's star co-owners previewed the match in a clip posted on social media. 

In the video, the highlights from the thrilling 3-3 draw at the Racecourse are shown.

As Wrexham score their second and third goals - which twice saw them lead the team 71 places above them - Ryan says: "And David put his hand in the bag and took out a stone and slung it.

"And struck the philistine on the head - and he fell to the ground."

 

This is in reference to Hoosiers - a film about a small-town Indiana high school basketball team that enters the state championship. 

Rob then interjects, saying: "That's a Hoosiers reference - wrong sport."

"Just go with it, Rob," Ryan replies.
