Isaac Price's hat-trick powered Northern Ireland to a stunning 5-0 win over Bulgaria that sent them top of their Nations League group.

After battering Belarus without reward in the opening 45 minutes of Saturday's goalless draw, Northern Ireland took their frustrations out on Bulgaria as Price became the first Northern Ireland player to hit a treble since David Healy in a 4-1 win over Liechtenstein in March 2007.
