Barcelona will consider purchase bids for Chilean forward Alexis Sanchez, who scored twice in his nation's World Cup campaign, club sporting chief Andoni Zubizarreta said Tuesday.

"In Alexis's case, there have been movements in the market and there have been proposals," Zubizarreta told journalists.

"We will seek a solution and if it is good for him and for us, we will analyse it."

The 25-year-old Chilean international has demonstrated a high level of ability in Brazil, sports director Zubizarreta said.

"He has shown his quality as a player and he has been possibly one of the best players in this World Cup," he added.

However, the Barcelona official ruled out any chance of the club selling 26-year-old Pedro Rodriguez, who plays in the same position.

"Pedro is not transferable. If we say we need to recover intensity, rhythm, speed, Pedro represents that," he added.

"I have no doubt he will be in the squad for 2014-15."

With two goals in the World Cup, one of them in the quarterfinals against Brazil in which Chile was eliminated on penalties, media speculation is mounting that Barcelona could lock in a high sale price for Sanchez to help finance other signings.

Barca also officially unveiled Ivan Rakitic on Tuesday, the Croatian international midfielder having signed a five-year deal witht eh Catalans.

The 26-year-old, former captain of La Liga rivals Sevilla and back from international duty at the World Cup, will take over the number four shirt vacated by Chelsea-bound Cesc Fabregas.
