Check out this Leo Messi hat-trick as he helped FC Barcelona to a 5-1 victory over Rayo Vallecano at the Campo de Vallecas, back in 2015. The forward netted Barça's third and his first of the game on 23 minutes tapping home a Neymar pass, before scoring his second on 53 minutes after Luis Suárez's shot had cannoned off the post. The Argentinian completed his hat-trick on 74 minutes, slotting home a pass from Sergio Busquets.
