Wigan Athletic and Boca Juniors are leading the chase for Argentine front-man Mauro Boselli, skysports.com understands.
The 25-year-old has been linked with a move to Europe, in particular England, a number of times over the past 12 months.
A move has thus far failed to materialise, but a transfer this summer looks likely, with Birmingham and Sunderland known admirers.
Wigan are now thought to have lodged a bid and are further ahead in their interest, but Boca Juniors are also keen for Boselli to return to La Bombonera with new coach Claudio Borghi a big fan.
Indeed Boca already own half of Boselli following two previous spells at the club, as Estudiantes only purchased 50 per cent of the player in 2008.
Now Boca are hopeful of taking him back to Buenos Aires, but agent Barry McIntosh, who has been overseeing Boselli's negotiations in Britain over the past 18 months, feels a move to the UK is now a distinct possibility.
"There is long-standing interest in Boselli from many parties, from around Europe and in South America," he told skysports.com.
"It is true that Wigan are now pressing ahead with their interest and are bidding close to the $10million (£6.9m) that Estudiantes are ideally looking for.
"But there is also Boca, and their new coach I know likes him a lot and they cannot be underestimated as they are still a very big club."
Asked about potential other suitors, McIntosh confirmed that Birmingham were one of a number of clubs who maintained an interest.
He added: "Birmingham have always liked him, as have other clubs in the Premier League, but things are progressing now and I can see something being done as early as next week."
