Lionel Messi scored an 86th-minute goal to earn all three points for Barcelona in a 1-0 win over Atletico Madrid on Sunday.
The first 45 minutes could not produce a goal but it was the host that had the better of domination, missing some good chances.
Barca returned from the break and were looking better, but their opponent showed they were playing to win.
With time running out, Messi combined with Luis Suarez to register her first-ever goal at the Wanda Metropolitano in a moment of magic.
Messi's late strike was enough to ensure the Catalan giants moved above Real Madrid to the top of the table, with Marc-Andre ter Stegen's two stunning first-half saves keeping his side alive.
On the eve of the Ballon d'Or announcement, it's Messi who makes the headlines with the winning goal that sends Barcelona top of La Liga.
Atletico slip to sixth and will feel hard done by not to take at least a point from that one.
