The Ghana star opened scoring for the Canary Islanders in what was a comfortable victory against their more established visitors Athletic Bilbao
It was the 29-year-old’s fourth of the season as he inches near his all-time best of six goals in a campaign, achieved with Schalke 04 two seasons ago.
The Ghanaian forward got onto the end of a dash down the flank by Brazilian right back Michel to tap home for the opener on 40 minutes.
His celebration was muted, instead facing the broadcast camera with his fingers shaped in the form of the letter “M”.
He was substituted at resumption of the second half having picked up an injury and was replaced by Momo who went on to score the second goal for the hosts.

Raul Garcia stepped up to take it and coolly slotted the ball down the middle after goalkeeper Javi Varas dived the wrong way.
But it was Jonathan Vieira that gave the hosts the final say when he pounced on a fast counter attack and cheekily flipped the ball over Kepa for a spectacular finish.
Las Palmas moved up into 10th position with 19 points while Athletic stayed rooted in eighth place with 20 points.
Boateng’s form this season has seen Ghana fans call for his return to the Black Stars since his suspension from the squad during the 2014 World Cup.
