Next up for Real Madrid are third-tier Cornella in the Copa del Rey, before Granada away in La Liga and Liverpool at home in the Champions League on 4 November.
Next for Barcelona is Celta Vigo at home on 1 November before they face Ajax away four days later.
Next for me is plateful of canteen chilli, followed by a cracking afternoon of Sunday football. See you there.

Luis Suarez has been doing a lot of talking recently.
"When I was a kid, I got sent off for headbutting a referee: I ran 50m to argue a decision, I was shown a red card and I headbutted him. I'm really not proud of that" is my favourite.
Our readers' vote is now shut and Cristiano Ronaldo takes home the man-of-the-match spoils with a very healthy 32.3% of the vote.
Isco (20%) and Dani Carvajal (12.7%) were closest to the nicking the award.
Neymar, the only Barcelona player on the list, attracted only 4.2% of your clicks.
Real Madrid 3-1 Barcelona
After that win might Gareth Bale, who missed today through a thigh injury, find himself riding the pine on the Real Madrid bench?
Manager Carlo Ancelotti says not: "Bale is a fundamental player for this team. He will play whenever he is fit.
"Isco was amazing but in order to beat Barcelona every one had to play as well as they did.
"I'm satisfied with our work. I'm proud of everyone."

It was a classic six-pointer tonight. A Barcelona win and Luis Enrique's side would have been seven points clear of Real Madrid and possibly over the horizon.
As it is, their lead is down to one point. The return at the Nou Camp in on 22 March. Mark the diary.

Luis Suarez did not have a single shot in his 69 minutes on the pitch. But don't take that stat too seriously.
He was straight up to speed, linking well with Neymar and Lionel Messi, getting an assist for Barcelona's goal and setting up another couple of chances.

Perhaps Luka Modric might get your vote as man of the match. The Croatia midfielder kept Real's Rolls Royce of a team purring and put himself about in defence as well.
