Athletic Bilbao beat Rayo Vallecano 1-0 on Monday to remain unbeaten after two games for their best start to La Liga since 2013.

Athletic, competing in this season's Champions League, moved to a four-way tie at the top of the table thanks to Oihan Sancet.

He won and converted a penalty in the 66th minute to join champions Barcelona, Real Madrid and Villarreal on six points.

Getafe have a chance to join this quartet later Monday when they face Sevilla.

Sancet made his mark on his return to action after three weeks on the sidelines with a knee injury sustained in a friendly against Liverpool.

On Sunday a brace from Kylian Mbappe helped Real Madrid to a 3-0 win over promoted Osasuna, 24 hours after Barcelona fought back from two goals down at newly-promoted Levante to win 3-2.
