Championship club Middlesbrough have rejected an offer of around £3m from a Middle East club for record signing Afonso Alves.
The Teessiders were contacted by an unnamed club, understood to be from the United Arab Emirates, about the 28-year-old Brazil international striker.
Boss Gareth Southgate said: "We have had a bid for Afonso, but it wasn't something we deemed to be acceptable.
"To be honest, it wasn't anywhere near what we would accept."
Alves joined Boro in January 2008 from Dutch side Heerenveen for a club record £12.7m, but has struggled to live up to expectations.
We have to accept we have players in the club who don't want necessarily to be here and how we deal with that is important Middlesbrough boss Gareth Southgate
He scored just four league goals in 31 appearances last season as the club were relegated from the Premier League.
Alves is among a number of big-name players who are expected to leave the Riverside this summer as they prepare for life in the Championship.
Boro have already lost Stewart Downing, who joined Aston Villa last week, and strikers Mido and Tuncay are also thought to be heading for the exit.
Speaking after Saturday's 3-0 friendly win at Macclesfield, manager Southgate insisted the club will use money from player sales to strengthen the squad.
"At some point we'll look to invest but we've got to see what the next few weeks bring," he told BBC Tees.
"We said at the start of pre-season we have to accept we have players in the club who don't want necessarily to be here and how we deal with that is important.
"In Downing, we've lost a player who was much liked by everyone in the dressing room.
"We wish him well, but we've got our own job to do."
Middlesbrough have already signed goalkeeper Danny Coyne and winger Mark Yeates this summer and Southgate now is likely to look at improving other areas of the team.
He said: "The balance of the squad is still strong.
"In terms of width, we've got Mark Yeates, Nathan Porritt, and Adam Johnson to come back in the next few games, plus Gary O'Neil who played in the middle but we know he's very strong out wide.
"So we have quality in those areas and it's probably other areas we'll look to strengthen as we go forward."
