The first team to sign Bale will not have the luxury of a buyout clause in their contract, but the Portuguese midfielder’s contract has a clause that could allow him to leave the club in the summer of 2018.
In the summer transfer window, Tottenham are the only team to have the option to buy out Bale’s contract.
Spurs have had a strong season, winning the Premier League and Champions League, and will be hoping to do better next term.
A bid to sign the Welshman could be rejected, however, with the Tottenham chairman Daniel Levy adamant that Bale will remain in London.
“He is a Tottenham player, he has been here since he was seven and he will be here for another three or four years,” Levy told BBC Sport.
“If we want to bring him back then we have to pay the price.
If we don’t want to pay it then we will see what happens next year.”
It is a situation that is very difficult to resolve, but we have not ruled it out.
“Bale will not be able to leave Spurs until 2021 and, with Tottenham’s contract expiring next summer, there is a high likelihood of the Welsh international leaving in the coming months.
If Bale were to sign for a rival club, there would be the risk of him leaving for free, and it would be difficult for Levy to sign a replacement.
The 23-year-old, who has a £150,000-a-week buyout, is regarded as a key player for Spurs, who have struggled to score goals in recent seasons.
He scored 10 goals in 22 appearances last season, helping Spurs to fifth place in the Premier Leagues.
Spurs are currently fifth in the table, with 14 points from 11 games, with goals scored a club-record six times this season.
