Marc-Andre ter Stegen has apologised to his Barcelona team-mates after the goalkeeper's mistakes helped Celta Vigo record a dramatic 4-3 victory at Balaidos, preventing Luis Enrique's men from going top of LaLiga.

The champions – who also lost at Celta last season – fell three goals behind in a dreadful first half that saw a poor clearance from Ter Stegen contribute to the hosts' opening goal through Pione Sisto.

Lionel Messi set yet another record on Wednesday, as he became the first man to break the 300-goal mark in La Liga.

The Barcelona superstar reached his triple-century in the 25th minute of his side's 3-1 victory at Sporting Gijon, opening the scoring with a typically unerring left-footed finish from 20 yards.

For good measure, Messi notched his 301st league goal with another clinical strike 16 minutes later. He is now 50 clear of second-placed Telmo Zarra in La Liga's all-time leading scorers' list.

The Croatian scored in the 21st minute when he arrived at pace to power in Arda Turan's cross from the left.

Lionel Messi, Luis Suarez and Turan also went close for the champions.

Neymar will make his return to Barcelona following the September international break after he was named in Brazil's squad for the World Cup qualifying matches against Ecuador and Colombia.

The 24-year-old forward captained the home nation to glory at the Rio Olympics, netting a stunning free-kick in Saturday's final before scoring the winning penalty to defeat Germany and prompt delirious celebrations at the Maracana.

Barcelona defender Javier Mascherano has been ruled out of his side's La Liga opener against Real Betis due to a hamstring strain.

The Argentina international suffered the injury during Barca's Supercopa de Espana success against Sevilla on Wednesday.

Mascherano came off to leave his team, who had used all three substitutes, to finish with 10 men.

Arda Turan gave further encouraging signs he can turn his Barcelona career around with a brace as Luis Enrique's side eased to a 3-0 win over Sevilla in the Supercopa de Espana second leg at Camp Nou.

The Turkey international's displays came in for regular criticism last season as he failed to find the form that persuaded Barca to prize him from Atletico Madrid.

The Spanish city had been due to host the first edition of the International Roller Sports Federation (FIRS) in 2017 after being awarded the Games last year.

Following elections in Barcelona, however, the new administration asked FIRS to be released from the promise they had made to stage the Games.

The governing body announced Nanjing in China as their replacements for the inaugural event in January.

Barcelona says on its club website that Neymar has been diagnosed "despite the fact that he had previously been vaccinated against the disease."

Neymar will miss both the European and Spanish Super Cups and is doubtful for the Spanish league opener.

Barcelona plays Sevilla in the European Super Cup on Tuesday. It then faces Athletic Bilbao in the Spanish Super Cup on Aug. 14 and 17 before visiting Bilbao again on Aug. 23 to start the Spanish league.
