Jonas opened the scoring when he headed home in the 10th minute at the Mestalla and the Brazilian forward sent Soldado clear three minutes later to make it 2-0 with a low shot past Genk goalkeeper Laszlo Koteles.
The pair combined again in the 36th minute when Soldado raced away from his markers and struck a powerful shot high into the net. The striker completed his hat-trick in the 39th with a tap-in at the far post from a Pablo Hernandez centre.
Pablo, who took the captain’s armband when Soldado was replaced by Aritz Aduriz, curled in a fifth in the 68th minute, Aduriz muscled his way through to make it 6-0 two minutes later and Tino Costa added the seventh in the 81st.
