Barcelona's pre-season got off to a perfect start against Gimnàstic Tarragona - check out their win here!
Koeman's much changed squad - which featured Pjanic and Rique Puig but was without new signing Memphis Depay - got off to a slow start in the Estadio Johan Cruyff. They went in 0-0 at the break, before the goals came pouring in after the hour mark. Manaj got his first on 60 minutes with a fine strike, before Collado made it two after 85 minutes.
Manaj got his second with a cool chested finish a minute later, before converting from the penalty spot with practically the last kick of the match to seal his hat-trick. After their convincing 4-0 victory, Koeman's side face Girona next on July 24.
