Referee JP Doyle certainly had his homework done ahead of Friday's game with Georgia and Argentina in the World Cup.
The Irishman, who was taking charge of his first game in this year's tournament, made a big impression on viewers and players with his display during the impressive win for the South Americans.
Doyle seemingly liked to get up close and personal with some of the players at the breakdown.

But it was his way of conversing with the players on both sides in various languages that seemed to grab most attention.

It seems that not only can he speak Georgian, but he also spoke French to a number of the Argentina players on the field too.

Although his performance away from showing off his polyglot skills left many frustrated.
