Aritz Aduriz scored a 92nd minute winner against Girona to give Gaizka Garitano a 1-0 winning start as Athletic Bilbao coach.
The veteran striker scored a late penalty after Iker Muniain had been brought down by Jonas Ramalho to give his team only their second win of the season.
It was the best possible end to Garitano’s first home league game in charge and moved Athletic level on points with Villarreal who are in 17th place in La Liga, one place out of the bottom three.
Girona had the ball in the net in the first half but Cristhian Stuani’s goal was ruled out when the video assistant referee spotted that he had handled the ball.
Aduriz' late match-winning kick was scored against Girona keeper Gorka Iraizoz , the striker's former team-mate at Athletic Bilbao.
Of his lobbed spot-kick past his old friend, Aduriz said: "I must have taken a thousand penalties against him so I had to come up with something different."
