Exhibition stuff by the world, European and Spanish champions. Messi to Suarez to Messi to Neymar...it's a delight to watch.

It's just a matter of how many Barca rattle up now. Betis' defence has been decimated by injuries and they are struggling badly against Messi, Neymar and Suarez.

Barca are turning on the style. Lionel Messi with the outside of his foot sends Luis Suarez clear again but the Uruguay striker cannot control the ball and the chance is gone. Brilliant pass.

A quite incredible statistic. Suarez's goal was a record 179th in a calendar year for Barcelona. Wow.

This could get messy for Betis. The second half is 55 seconds old when Sergio Busquets threads a terrific defence-splitting ball for Luis Suarez to slot low past the advancing keeper. Game over.

It must be the stuff of dreams to join Barcelona.

Yet within hours of signing for the club's reserve team, forward Sergi Guardiola was sacked after officials were alerted to "offensive tweets" he had posted two years ago about Barca and Catalonia.

Guardiola, 24, joined Barcelona B on Monday but according to Marca , external , the Spanish national daily sport newspaper, his contract was terminated "some hours later" when they became aware of pro-Real Madrid tweets, , external including offensive language about Catalans.

Guardiola started this season at Madrid-based club Alcorcon in Spain's second tier.

There is one more game in La Liga in 2015 after tonight. Gary Neville says it is time for his players to show the "real Valencia" as he seeks his first La Liga win as boss.

Valencia are without a win in five league games and are away to Villarreal on Thursday before hosting Real Madrid on 3 January.

"I'm still comfortable we can have a very good season," said Neville, who has overseen three successive draws. It's time for us to get results that go with our efforts. We need to see the rewards of the work we've done."

There will be text commentary of Valencia's game on the BBC Sport website.

Two minutes of added time.

Barcelona are heading back to the top of La Liga after a penalty that shouldn't have been and a goal from a player who looked as though his night had come to an end.

This is a night to forget for Betis. They have lost a second player to injury. Defender Heiko Westermann, who scored the own goal, cannot continue after a challenge and is replaced by Dider Digard.

A great chance for Luis Suarez to make it 3-0...but he somehow fires into the side netting when it was easier to score.

What an incredible passage of play. Betis looked comfortable before falling victim to a poor penalty decision. Lionel Messi is forced off for treatment and then scores moments after coming back on.

Pepe Mel is still livid with the referee for awarding the penalty and has been sent to sit in the stand.
