Goalkeeper Mark Schwarzer is hopeful Middlesbrough will come up with a new offer for him to stay at the club.
Goalkeeper Schwarzer is on international duty with Australia
The 34-year-old, who is currently with the Australian squad at the Asia Cup, rejected a new deal earlier this month.
But he still wants to stay and said: "My agent is speaking to Middlesbrough and at the moment it's between him and the club to try to sort out something.
"As far as I am concerned, I'm just concentrating on the tournament and I hope the rest will sort itself out."
After Schwarzer turned down the initial offer his agent Shep Messing stated: "Middlesbrough asked what Mark wanted and we confirmed his wish to remain at the club.
"We put forward a sensible and fair proposition for both player and club. We have received a proposal from the club and, at this point, we have been unable to agree on terms."
Talks are ongoing but we do not and will not conduct our negotiations through the media
Boro chief executive Keith Lamb
Schwarzer had earlier blamed Mark Viduka's exit on the club's failure to seal deals early enough and said he could leave for the same reason.
Viduka, 31, left Boro to join Newcastle on a free transfer after his contract expired.
"I've taken it to be quite normal at Middlesbrough, they do leave things very, very late," added Schwarzer.
"They tend to do things only when they're under pressure."
Schwarzer's public outburst was criticised by Boro chief executive Keith Lamb.
He commented: "Talks are ongoing but we do not and will not conduct our negotiations through the media."
