Barcelona midfielder Sergio Busquets has praised new signing Pierre-Emerick Aubameyang after his display for the club over the weekend. Aubameyang scored a hat-trick as the Blaugrana thrashed Valencia 4-1 in Lga at the Mestalla last night (February 20).The Gabonese forward had failed to open his account for the Catalans in the three matches he played previously. However, Aubameyang was on fire against Los Murcielagos, scoring twice in the first half and adding a third in the final half an hour.Speaking after the match, Busquets lauded the striker's impact and said (as quoted by Barca Blaugranes):“Since Auba arrived he’s been working hard. We knew he hadn’t played much but this is the second game he’s started. He’s a fabulous player and having him in the squad is a real luxury for us.”FC Barcelona@FCBarcelonaMr Hat Trick talks about Barça's 4-1 win at Valencia@Auba5:31 AM · Feb 21, 20224027237Mr Hat Trick talks about Barça's 4-1 win at Valencia@Auba https://t.co/wgzMptdyS0The Spaniard also praised Barcelona's performance, adding:“It’s been an important win today.
