Barcelona sporting director Eric Abidal admits the club are waiting for an answer from Ajax midfielder Frenkie de Jong on whether he wants to join them.
The 21-year-old is considered to be one of the very best young players in world football, and has reportedly attracted interest from some of Europe's biggest clubs, including Paris Saint-Germain.
Abidal admits Barca are among the clubs vying to sign De Jong.
"This question has to be asked to the player. He knows there is interest from many clubs and he will make his decision," Abidal said. "We can only wait, like everyone else."
De Jong made his international debut for the Netherlands in June, against Peru, and has since won five caps.
He has played 16 times for Ajax in the Eredivisie this season, scoring four goals.
Barcelona have already made two signings in January, with Kevin-Prince Boateng moving from Italian side Sassuolo on a six-month loan deal with an option to buy, and defender Jeison Murillo also joining on loan from Valencia.
Abidal said departures are also possible this month, with Malcom and Denis Suarez among those linked with moves away.
"We are happy with the squad but there is always a chance," Abidal said. "Players who are not playing very much can stay or leave, all scenarios will be evaluated."
