It's taken 20 minutes for Lionel Messi to really get the ball but he's immediately fouled. The free-kick comes to nothing.

At the other end, Nordin Amrabat squeezes through two Barca defenders but his curler from 20 yards is high and wide.

Leganes have the chance to break at pace but Javier Eraso dawdles and Barca get the ball away.

The Catalans then counter but Luis Suarez concedes a free-kick as he tries to shake his defender.

Leganes are starting to come back into it more, but yet to create a chance. Nabil El Zhar tries - and fails - to lose Samuel Umtiti and Barca come away with it.

It's been all Barcelona so far. The leaders are wearing their blue highlighter jerseys. Luis Suarez appears to be holding his knee after being brought down (fairly) in the box. Worrying for Barca.

It's half-time in Munich, with Bayern 2-0 up.

Second-placed RB Leipzig are drawing 1-1 at Bayer Leverkusen. Timo Werner had given the fizzy drink boys the lead from a penalty but Leon Bailey levelled just before the break.

Luis Suarez puts the ball in the back of the net, but Jordi Alba was offside in the build-up before his pass to the Uruguayan. Leganes had stopped playing.

We are under way.

Barcelona, Roma derby, Madrid derby, Napoli, Bundesliga, Ligue 1 - we're discussing it all today.

German Bundesliga

Bundesliga leaders Bayern Munich are playing in a Bavarian derby as they bid to extend their unbeaten run since Jupp Heynckes took over.

They have won six out of seven since his arrival, and the one which technically wasn't a win was still a penalty shootout success.

They are four points above RB Leipzig and can go nine above third-placed Borussia Dortmund - who lost to Stuttgart last night.

That game kicked off at 14:30 GMT and it's already 2-0 thanks to goals from Arturo Vidal and the new-look Robert Lewandowski.

Up front for Barcelona, Paco Alcacer makes only his third La Liga start of the season. He scored twice against Sevilla in the game before the international break.

Barca are short of choices at centre-back, and Gerard Pique and Samuel Umtiti both start despite being a booking away from missing next weekend's game with title rivals Valencia.

Leganes striker Nordin Amrabat - on loan from Watford - is still chasing his first goal of the season.

Leganes: Cuellar, Zaldua, Munoz, Siovas, Diego Rico, Ruben, Gabriel, El Zhar, Eraso, Szymanowski, Amrabat.

Barcelona: Ter Stegen, Semedo, Pique, Umtiti, Alba, Rakitic, Busquets, Iniesta, Messi, Alcacer, Suarez.

Barcelona are four points clear of Valencia at the top of La Liga - and EIGHT above both Real and Atletico Madrid.

They are unbeaten in all 11 La Liga games since Ernesto Valverde's appointment this summer, winning 10 of them.
