Gareth Bale's agent has hinted that the Tottenham Hotspur star could leave White Hart Lane this summer.
Jonathan Barnett admitted that the recent departure of manager Harry Redknapp could influence the Wales international to seek a move elsewhere.
"Yes, it is clear that this is a problem," he told Spanish newspaper Sport.
"The big European clubs already know how much it would take to do the operation and therefore if you are interested you know what kind of offer has to be put on the table."
Redknapp's exit and Spurs' failure to secure Champions League football last season have given rise to speculation of a mass exodus from the club over the summer.
Luka Modric has been tipped to complete a move to Manchester United after Euro 2012 has concluded.
