Txiki Beguiristain has admitted that signing Santiago Ezquerro and Eidur Gudjohnsen may have been mistakes as Barcelona did not expect their youngsters to flourish so quickly.
The duo have become fringe players at Camp Nou following the sudden rise of such talents as Giovani Dos Santos and Bojan Krkic and could be sold if a suitable offer comes in.
"There will always be mistakes because you have to have the players who are numbers 21, 22 and 23 in the squad," Beguiristain told RAC 1.
Barca's technical secretary revealed that while Gudjohnsen is confident of winning back a place in the side, Frank Rijkaard and his staff prefer to use the new kids on the block.
"Gudjohnsen believes that he still has a chance here, but at the moment the coaches are giving more time to Giovani and Bojan," he explained.
Neither Ezquerro nor Gudjohnsen have played a single minute for Barcelona this term and the Spanish giants may look to use the January transfer window to move them on.
"If Ezquerro and Gudjohnsen are not given playing time then we will have to look for a situation that suits everyone," Beguiristain added.
"What is clear is that if there is an offer then first of all we will have to talk to the player. I know that Ezquerro is thinking about playing abroad."
Gudjohnsen was linked with Manchester United over the summer and was also said to be a target of both Newcastle and West Ham.
Ezquerro has reportedly been interesting Premier League sides such as Everton and Bolton, but he was keen on a return to Athletic Bilbao in the summer.
