Rarely could a football manager been as happy as Hansi Flick was after 24 minutes.
That was the moment when the official signalled that Fermin Lopez’s first goal would stand, and it meant that the Blaugranes were already four goals to the good.
Fermin would add his second and Barca’s fifth before the half-time whistle blew with another stunning finish, and it capped off what has to be one of the most one-sided halves of football ever seen in the Spanish top-flight.
The fact it could’ve easily be seven or eight by then shouldn’t be overlooked either.
