It was in the 18th minute that "Teresa" - as it says on her back - got the ball out to the left and advanced into the center outside the penalty area.
She dropped the ball to Jessica Villagra, before getting it back and pushing right away.
The 21-year-old midfielder got what you could without exaggeration call a dream hit and could see the ball - via the crossbar - find the net mesh up to 1-0.
Swedish star Sofia Jakobsson was in the starting eleven and had to start out on the left wing in a 4-3-3 formation.
Real Madrid's other Swedish star, Kosovar Asllani, started the match on the bench.
But after the visitors equalized on penalties at the start of the second half, Madrid made a triple change where Asllani came on the pitch after an hour had been played.
Barcelona won big
However, there were no more goals in the match but it ended 1-1.
Real Madrid thus stayed at 74 points.
Superior Barcelona played with Eibar in their last match where they won 9-1 and led 6-1 already into the break.
In total, Barcelona scored 167 goals in 34 matches - and conceded 15. The only loss of the season came against Atlético Madrid a few rounds ago when they fell 0-1 where the Swedish goalkeeper Hedvig Lindahl zeroed the champions.
Lindahl closed again today when Atlético won 1-0 against Levante.
