"If we don’t [qualify for the Champions League], we have to sit down and discuss what's best for myself," Bale told BBC’s 'Football Focus'.
The Welshman lit up last season’s competition with a number of impressive performances, including a hat trick against Inter at San Siro, and in turn alerted a host of European giants such as Barcelona and Real Madrid.
Spurs had looked on course to seal a return to the top four in the current campaign, but a recent dip has seen them drop below Newcastle into fifth place, with Bale in turn suggesting he may move elsewhere to secure Champions League football.
Despite uncertainty over his long-term future, the former Southampton man is hopeful that Spurs can overcome their recent blip in a similar fashion to rivals Arsenal.
"We're playing some good stuff at the moment, we just can't seem to get the ball in the back of the net," he explained.
"I think it's just one of those things you go through during the season - I think Arsenal went through it and came out stronger so hopefully our luck will change. We're not getting too much luck at the moment."
"Things can change dramatically in football, and we're hoping it changes for us over the last four games."
