Barcelona coach Xavi hopes their young midfielders Pedri and Gavi can go on to do better than the famous Barca midfield he starred in.
Xavi, Andres Iniesta and Sergio Busquets were Barca and Spain's midfield trio for many years - winning multiple trophies for club and country. Busquets is leaving the club at the end of the season, while Iniesta moved to Japan five years ago.
"We are working on forming a new [era]," Xavi said.
"I hope players like Gavi, and Pedri, can even go beyond us, that is life, that is sport. I hope they can surpass us. There's a very good batch, home-grown players and midfielders especially.
"I hope they follow in Busquets' footsteps and can achieve as much success as he has, a new era is beginning."
On Busquets, Xavi said: "He's the best defensive midfielder I've ever seen. Not being nominated for the Ballon d'Or was an injustice."

Lewandowski is two ahead of Karim Benzema in the golden boot race.

Barcelona boss Xavi is set to add a La Liga title to the eight he won as a player.

"We're at 200%," he said in a mathematical impossibility.
"I'm seeing them train at full pelt with hope, desire and intensity, to win La Liga."

Atletico Madrid, who started the weekend in second place, lost 1-0 at Elche this afternoon - their first league defeat by those opponents since 1985.
That means they can't catch Barcelona now. Not that they were going to.
