Barcelona coach Xavi admits they need to buy a replacement for captain Sergi Busquets.

The midfielder will leave Barca at the end of the season.

"Whoever is the most complete, whoever is the best pivot to replace Busquets. We depend on fair play and the economic situation. The profile must be a very decisive player, a player who is strong to wins duels and is intelligent, technically sound. The natural replacement for Busi," said Xavi.

On players similar to Busquets to come through La Masia, Xavi insisted: "Yes, there have been some. Samper, Oriol Romeu? Yaya Toure had to leave, a spectacular player. We've been lucky that Busquets has never been injured. Players eventually decide that they have to leave. Now it's time to find a replacement because we're not sure if we have one at home.

"We have to find that piece if we want to compete next year, it's fundamental. Busi has been vital this year, very important. We have to find a very important player, it is key to be able to compete next season",
