A Fermin Lopez hat-trick and two goals from Marcus Rashford powered Barcelona to a crushing 6-1 Champions League victory over Olympiacos on Tuesday, with the Greek side left fuming over a controversial red card early in the second half, Reuters reported.

The match got off to a flying start when Fermin opened the scoring from a rebound in the seventh minute. The 22-year-old pounced on a loose ball after Lamine Yamal's shot was parried by the Olympiacos goalkeeper.

Fermin smashed the ball into the back of the net and he doubled his tally in the 39th minute by finishing off a lightning-quick counter-attack, according to Reuters.
