It's almost time to go. Can Dortmund win to move to within three points of Bayern? Or will Bayern go back above RB Leipzig at the top?

Borussia Dortmund manager Thomas Tuchel: "It is a good opportunity for us to surpass ourselves.
"It is football, anything is possible. We are going through a phase during which many things simply are not going our way, and there is much we need to work on.
"[It is] no bad thing in a game against Bayern Munich that we do not simply take to the field in a purely technical or tactical manner.
"There is a third plane on which we must fight. We need passion, aggression when defending, a proactive attitude, and we must be brave.
"That is key in this game, and that will get the viewing public on our side. In this way, we will be able to give as good as we get technically and tactically."

Borussia Dortmund v Bayern Munich (17:30 GMT)
Bayern Munich will take their place at the top of the Bundesliga if they win today. There is an unfamiliar name at the top of the pile at the moment - RB Leipzig, who beat Bayer Leverkusen 3-2 last night.
Dortmund, who have won only one of their last five league games, are fifth. A win today would take them to within three points of Bayern though.

No rest for the wicked and we immediately turn our attentions to another huge game on the continent - Der Klassiker.
Barcelona 0-0 Malaga
Malaga were furious that four minutes of injury time became almost eight minutes. But they did have two players go down injured and make a substitution. Not sure they had any moral high ground. Anyway, all's well that ends well (for them).
NINE-man Malaga hold on for a point after withstanding constant Barcelona pressure. It got really tense at the end. The champions miss the chance to go top.
Barcelona 0-0 Malaga
Chaos. Malaga are down to nine men - Juan Carlos is sent off. For dissent maybe
Barcelona 0-0 Malaga
Barca have a last-minute corner.
Barcelona 0-0 Malaga
Carlos Kameni makes another brilliant save from Andre Gomes, I think. We're well become the added time.
