Andrei Voronin's advisor is refusing to comment on speculation linking the Liverpool striker with a move to Valencia.
The 29-year-old is currently enjoying a very successful season-long loan switch at Hertha Berlin, with his goals helping the club move to the top of the Bundesliga.
Voronin said earlier this week that he had no intention of returning to Anfield and his advisor, Andrei Golowasch, has now told Bild: "We have had a number of enquiries but I don't want to comment.
"We have had a very positive discussion with Hertha. Now we need a concrete decision. Perhaps there will be something new in the next few weeks."
However, Hertha are keen to tie up a permanent deal for the Ukraine international, with general manager Dieter Hoeness saying: "We will do all we can to keep Andrei in Berlin.
"But there are no guarantees. If we can't find a way, then we'll have to look at other possibilities."
Veteran Bayern Munich midfielder Ze Roberto hopes the club offer him a new contract that will keep him at the Allianz Arena for at least another two seasons.
The 34-year-old Brazilian's current deal expires at the end of this term and he has only been offered a 12-month extension.
He insisted: "I feel like a 25-year-old. I am in the best form of my life and I feel that I can play for another two or three years.
"That is why I thought that maybe one year is too little."
Bayer Leverkusen midfielder Arturo Vidal is unlikely to play again this month after it was confirmed that he suffered severe concussion during the 1-1 draw with Bochum.
The Chile international sustained the injury in a clash of heads with Bochum's Marc Pfertzel in the 37th minute of the Bundesliga clash and had to be taken to hospital.
"We hope he does not need an operation," said Bayer coach Bruno Labbadia.
Vidal also fractured his eye socket in the incident and is expected to be sidelined for at least four weeks.Reuse content
