Thanks for joining us today. The big game tomorrow on the continent is title-challenging Inter Milan v struggling Serie A champions Juventus. That one's a 19:45 BST kick-off - with the live text starting around 19:15.
The top of La Liga has a familiar look to it. Real Madrid are top from Barcelona on goal difference.
But that could change tomorrow when Villarreal play Celta Vigo (11:00 BST). A win for the Yellow Submarine would take them back to the top, while a Celta victory would see them squeeze in between the top two on goal difference.
The last time Barcelona finished a La Liga game with less possession than their opponents was September 2013 - also against Rayo Vallecano (45.73%).

Barca have conceded 11 goals so far in eight games. This time last season they hadn't conceded one!
A year ago tomorrow they became the first La Liga team in history to open a season with eight consecutive clean sheets.
I know some people admire good defending as an art. But give me total chaos and mayhem any day.
A brilliantly farcical game where defending was seemingly banned comes to an end.

Rayo keeper Tono had gone for a walkabout and Luis Suarez considers chipping him, but instead tries to play it to Munir El Haddadi, but a defender cuts it out. Probably should have been 6-2 there. We're in the last minute now.
Jozabed
Barcelona fail to deal with a cross properly and Jozabed volleys into the bottom left-hand corner. Rayo have deserved a goal for their second-half performance.

Rayo Vallecano haven't stopped playing yet and Patrick Ebert blazes a shot over after Gerard Pique fails to clear properly.

Luis Suarez
Four goals and an assist for Neymar. This time the Brazilian crosses to Luis Suarez, who smashes home at the far post.
This scoreline doesn't tell the story of the game at all. Rayo were dominant at the start of the half.

Luis Suarez clashes with Rayo defender Ze Castro and the Uruguayan is holding his teeth...
But this time he hasn't tried to eat his opponent, it was only a clash.
