Athletic Bilbao hosted Atletico Madrid at the new San Mames, recalling that the visitors were the first team to win at their new ground.
Atletico knew they had to win to regain top spot following FC Barcelona's 1-0 win over Espanyol earlier in the day.
Both sides entered the game in fine form; Athletic were unbeaten in six matches, while Atletico had not suffered defeat in the last five, including four victories.
Despite Athletic taking an early lead through Iker Muniain, Diego scored for the fifth consecutive match in a row to level proceedings. Then, just five minutes before the hour mark, Koke nodded in the winner, which puts Los Colchoneros back to the top of La Liga.
Let's take a look at six things we learned from Atletico's 2-1 victory.
