Genoa made the most of truly terrible defending to take all three points from Cagliari in this five-goal thriller.
The Grifone welcomed Armando Izzo back for his first appearance of the season after a ban for not alerting authorities to potential match-fixing while he was at Avellino. Andrea Cossu and Federico Melchiorri missed out, while the visitors lost Nicolas Spolli.
The visitors took the lead, as Artur Ionita was caught in possession, Andrej Galabinov springing the offside trap on an Adel Taarabt through ball.
An almost identical move threatened a second goal, but this time Galabinov fired off target, while Mattia Perin parried a Fabio Pisacane volley.
The Sardinian defence was AWOL as Alessio Cragno parried another Galabinov attempt set up by Taarabt, then the goalkeeper flew for a one-handed reaction save on Luca Rossettini’s header.
Genoa got their second when the offside trap failed miserably yet again for Galabinov, whose pass was back-heeled by Luca Rigoni into the path of Taarabt for a low drive.
The hosts were simply awful and van der Wiel’s Serie A debut was short-lived, but substitute Paolo Farago created a goal within a couple of minutes, his cross nodded in by Leonardo Pavoletti for his first Serie A goal in a year.
Joao Pedro almost completed the comeback for 2-2 moments later, his right-foot curler inches off target from outside the box.
Cagliari lost goalkeeper Cragno to a muscular problem, giving Rafael his comeback after a long injury lay-off.
Genoa restored their two-goal cushion thanks to Rigoni’s towering header from a corner.
However, Rosi then handled in the Cagliari box and after consulting VAR, the hosts were awarded a penalty converted by Joao Pedro for 3-2.
It remained wide open and Diego Laxalt’s curler on the counter-attack came off the far post, then Rafael denied the Galabinov follow-up and Stephane Omeonga hit the side-netting.
