Luis Enrique trusts me - Sergi Roberto

The Barcelona midfielder also believes that the departure of Xavi and the fact that Arda Turan cannot play until January will work in his favour

Sergi Roberto is confident of playing a more important role at Barcelona this season, revealing that coach Luis Enrique has told him that he has the utmost faith in his ability.

The 23-year-old has shown promise over the last few years since his emergence from the Blaugrana youth system but has been unable to nail down a regular starting berth due to the presence of Ivan Rakitic, Sergio Busquets, Xavi and Andres Iniesta in the first team.

While Xavi departed the Camp Nou side this summer to join Al Sadd, Arda Turan has been recruited from Atletico Madrid, though the Turkey international is unavailable to play until January because of the club's transfer ban.

Roberto thus believes that he will see more game time during the 2015-16 campaign, not least because of the unwavering support of his boss.

"Luis Enrique told me that he trusts me," he told reporters. 

"What I want is to play more games and help the team. I hope to play more minutes than last year. Being versatile is good for me, but I don't know where I will play.

"Last year, Xavi was ahead of me, now this year it's Arda. But he can't play until January, so I have a chance.

"I played as a defensive midfielder last year to give Sergio Busquets a rest and this year I may get the chance to play in the side."

The midfielder is expecting a bright start to the season for Barca, as they prepare to add to last year's treble when they compete in the Uefa Super Cup and the Supercopa de Espana.

"We have two finals in the next week," he said. "Last season was a great season but now we have a chance to win two more titles.

"Then, if we win the Club World Cup [in December], we will have won six trophies, which would be great for the team."

Roberto played just 12 games in La Liga last season, but made 17 appearances in the top flight the year before.
