Hleb has long since been rumoured to leave the club he joined back in 2005 for £11.2m, and Barcelona are one of the clubs most interested in him.
Indeed, it seems that Barça are now heading the queue for the Belarussian in light of the fact that Inter have pulled out of the race.
Ferber said, "We have had talks with Barcelona but nothing has been signed.
"I'm sorry that we won't be able to take him to Italy, he liked Inter a lot but obviously Mourinho has made some different choices and has gone for some other names."
The ex-Stuttgart man, who has one year left on his contract, is also wanted by Real Madrid.
