Juventus v Roma (19:30 GMT)
Italian Serie A
Will the football ever stop? Now it's time to look at a big Serie A match.
Barcelona 2-0 Celta Vigo
Easy as you like for Ernesto Valverde's side.
They're three points clear once again at the top of La Liga thanks to goals from Ousmane Dembele and Lionel Messi.
Barcelona 2-0 Celta Vigo
We're into stoppage-time now. It's job done for Barcelona who have cruised for much of this.
Barcelona 2-0 Celta Vigo
Celta earn a corner but it's an easy catch for Marc-Andre Ter Stegen.
The Barca goalkeeper has certainly seen more of the action in the second half but he's rarely been challenged which will be a big disappointment for the visitors.
Barcelona 2-0 Celta Vigo
The visitors have undoubtedly grown into the contest possession-wise as the game has developed, but they've been lacking in the final third and are quickly running out of time.
Barcelona 2-0 Celta Vigo
Sergio Busquets exits the field to a standing ovation. Another effortless display.
On comes Carles Alena for the final five minutes or so.
Barcelona 2-0 Celta Vigo
Was that the chance for Celta?!
Robert Mazan, perhaps frustrated, strikes from distance and manages to earn his side a corner.
The resulting cross isn't dealt with and a scrap ensues right in front of Marc-Andre Ter Stegen's goal - but the Barca keeper eventually gains control of the situation.
Barcelona 2-0 Celta Vigo
A final roll of the dice for Celta Vigo as the game looks to be getting away from them.
Southampton loanee Sofiane Boufal is replaced by Pione Sisto.
Barcelona 2-0 Celta Vigo
Oooft that was very close to a third.
Nelson Semedo fires a shot from the right which is blocked by Ruben Blanco. It falls back out into the six-yard area however and Lionel Messi is charging in as Blanco rushes to gather.
Celta survive for now, but they desperately need the next goal to be theirs.
Barcelona 2-0 Celta Vigo
Barcelona are looking comfortable on this lead and they've been relatively untroubled since the interval.
That said, Philippe Coutinho is warming up for the hosts who clearly don't want to settle for two.
Barcelona 2-0 Celta Vigo
The home side make their first change of the evening as Arturo Vidal makes way for Arthur Melo.
Barcelona 2-0 Celta Vigo
A chance for Barcelona to put the game to bed at the other end now, as Lionel Messi finds himself in space in the Celta Vigo penalty area.
He chooses to try and pass to Luis Suarez but fails to reach his target and Celta can clear.
Perhaps he should've taken the early shot, but who am I to question him.
Barcelona 2-0 Celta Vigo
That was a chance for Celta Vigo.
Brais Mendez sends a curling shot narrowly wide of Marc-Andre Ter Stegen's right post from the edge of the area.
It was a great effort, but now Celta need to build on that if they're going to get back in this.
Barcelona 2-0 Celta Vigo
19-year-old Fran Beltran comes on in place of Aspas.
He's a summer addition for Celta, moving from Rayo Vallecano. Can he have an impact on this one?
Barcelona 2-0 Celta Vigo
Iago Aspas is struggling early in the second half, and it looks like his game is done.
There's plenty of applause for the forward as he limps off the field - that's a blow for the visitors.
Barcelona 2-0 Celta Vigo
There's one change to report for Celta Vigo at the break, as Stanislav Lobotka enters the midfield in place of Okay Yokuslu.
Barcelona 2-0 Celta Vigo
Celta Vigo get us back under way.
Barcelona 2-0 Celta Vigo
Barcelona have emerged first for the second period, ready to finish the job.
Barcelona 2-0 Celta Vigo
Importantly, Barcelona are heading three points clear at the top of La Liga as it stands.
They're also on course to make it four league games without conceding. So far that doesn't seem too unlikely - but Celta Vigo will be looking to compete much better in the second half.
Barcelona 2-0 Celta Vigo
The home side enjoyed just shy of 60% of the possession in that first half, but Celta Vigo did grow in confidence going forward as the half went on.
But, as they have been in recent weeks, Ernesto Valverde's side have been too slick for their opponents who look somewhat off the pace.
Can they improve after the interval?
