When it comes to Premier League derby matches, the vast majority of us on this side of the planet would make a point of tuning into the derbies of Manchester, Merseyside, North London or the North East.
Not so in the United States however.
US broadcasters NBC paid over €180 million for the rights to screen Premier League games and their figures show that the most watched Premier League match in the United States was the small matter of the Wales derby.
On February 8th, 1.24 million viewers tuned into NBC to watch Swansea beat Cardiff City 3 - 0 at the Liberty Stadium, in Gary Monk's first game in charge.
In fact, the Swans were also involved in the second most watched match, with 1.10 million people sitting down on their couches for the club's 2 - 0 defeat to Manchester United.
Only two other matches broke the million viewer mark with both of those involving Man United. Their 2 - 0 win over Crystal Palace in February attracted 1.06 viewers and the 3 - 1 loss to Chelsea in January bringing in 1.02 million.
