Adriano is now ranked the fourth highest scorer at the club following a win which consolidated their place at the top of La Liga.
Adriano told the club website: "I'm very happy to be able to score goals for the team.
"I have never scored so many goals at this point of the season."
Adriano revealed the victory was built on the team adapting the right approach to the game.
"We were very serious from the start, the first half was fantastic.
"We prefer to play against teams that want to play their football (like Athletic), it makes you more focused and it forces to play at your best."
