Middlesbrough boss Tony Mowbary admits he is unlikely to keep Julio Arca this summer.
The Argentine is out of contract at the end of the season and he has intimated he would like to extend his stay on Teesside.
Arca joined Boro from rivals Sunderland in 2006, but Middlesbrough are not in a position to offer him similar terms.
Skysports.com revealed Premier League interest in Arca in January, and Wigan are understood to have made a move for him on deadline day.
The Latics remain interested, along with clubs from the continent, and Mowbray concedes Boro are unlikely to be able to offer him a suitable deal.
"There's not a lot we can do about Julio," said Mowbray. "He was signed when we were in the Premier League and he's on Premier League money.
"His contract is expiring at a level that is unsustainable for us. I really like him as a footballer and a man. He really buys into the way we want to do things, and his performance level suggests he likes the way we're trying to do things.
"There's a perception that he must be old because he's been around so long, but he only turned 30 a couple of weeks ago. He has a lot of football still to play, and a lot of earning power in the remainder of his career.
"Reluctantly, we have to admit there's a fair chance that, come the summer, Julio will leave."
Boyd and Davies
Mowbray also revealed that there was interest from Major League Soccer in signing Kris Boyd.
The former Rangers striker was strongly linked with a move back to Ibrox in January, while there was also interest from Russia and Turkey.
Mowbray admits talks had taken place about Boyd leaving, adding "There was a little bit of discussion about Kris possibly moving to America a few weeks back. But I don't think that's going to happen now."
Boro are looking to push ahead with their interest in Andrew Davies.
The former Boro youth star is currently with Stoke but Mowbray is hoping a loan deal can be thrashed out.
"There's a potential for a loan deal to happen," confirmed Mowbray.
"Andrew was here for four or five weeks, but the weather meant we didn't see a lot of him.
"He wasn't really ready then because he hadn't played any football for 18 months. We were basically facilitating him training and getting right.
"His fitness is better now though, and I've asked the question to Stoke. The difficulty is finance. We're not really in a position to add an extra salary on top of the salaries were already paying.
"It will need an agreement with Stoke, and that agreement will have to be financially favourable to us. There's the potential for something to happen because he's not in their 25 and he's not going to play. I think they've had other inquiries, but knowing Andrew, if there's a potential to move on loan, I think he'd like to come here."
Boro are currently without captain Matthew Bates and Stephen McManus and having also lost David Wheater in January, are short in central defence.
