Tottenham director Sir Keith Mills believes they will have to sell Gareth Bale to Real Madrid.
Real Madrid coach Carlo Ancelotti revealed last week that the nine-time European champions were in talks with Spurs over a possible deal for Bale, for a reported fee of £86m.
"We very much want Bale to stay," Mills told the London Evening Standard. "If a player is desperate to leave, it's very difficult to force him to stay.
"We've seen it in other clubs. Even if he has a contract, you can't force somebody to play for you.
"This summer, we are investing in a great squad and we hope that provides us with Champions League football next year and we start to win trophies, FA Cups. That's what Tottenham need. We have made some good acquisitions."
