The 23-year-old winger has been in sensational form for the north Londoners this season, netting 22 goals in 37 appearances for Spurs this term.
Bale’s stunning displays have inevitably triggered speculation linking him with a move away from White Hart Lane.
However, former Wales goalkeeper Southall believes his fellow countryman should stay in north London and see how the club develops in forthcoming seasons.
“I think he will stay at Tottenham and I think he should stay at Tottenham – but if they don’t expand, he should leave,” Southall told the Daily Express.
“To be recognised as one of the best players in the world, you have to be playing at the top level – but I don’t think that’s a reason to leave Tottenham. At the moment, it’s the right place for him to express himself.
“He’s young enough now to go abroad and learn a new language and, if he leaves, he has got to go to Spain.
“That would be a massive opportunity for him to learn about himself and the game, but he shouldn’t do that for another couple of years.”
