Two goals by Ibai Gomez helped Athletic Bilbao come from behind to beat Valladolid 4-2 at the new San Mames stadium in the Spanish soccer league on Monday.
Valladolid opened the scoring against the flow of play when Oscar Gonzalez struck the back of the net from what appeared to be an offside position in the 15th minute.
But in an eventful last 25 minutes, Gomez pounced on Valladolid goalkeeper David Marino's punched-out save to equalise in the 65th, before Oscar de Marcos added another for Athletic 10 minutes later.
Gomez doubled his tally in the 82nd and Ander Herrera made it 4-1 four minutes later.
Valdet Rama pulled one back when he beat three Athletic defenders before shooting into goal in injury time.
The victory lifts Bilbao back into fourth place on the La Liga table.
