Talks between Spurs and Real Madrid appear to have reached an impasse in recent weeks, but with two weeks of the transfer window left, there is still a chance that Tottenham forward Bale could complete a world-record move to the Spanish capital.
The London club are expected to push on with their pursuit of Anzhi Makhachkala forward Willian, who would be a natural replacement for Bale, while summer signing Nacer Chadli and Germany international Lewis Holtby can also operate in that position.
Yet Sigurdsson showed promise when he played in that role against Crystal Palace on Sunday afternoon, even though he missed a second-half chance to kill the game off.
The Iceland international performed well when he moved in to a central role towards the end of last season and he is more than happy to stay there for the rest of the season.
"It was nice to play there again," Sigurdsson said following the 1-0 win.
"I enjoy playing there.
"Hopefully I'll stay there behind the striker because (Roberto) Soldado and Jermain (Defoe) are top strikers and it's good to play behind them.
"I'll play anywhere the gaffer wants me to, but that's one of my better positions, playing behind the striker. That's what I prefer."
Villas-Boas ruled Bale out of Tottenham's Europa League playoff against Dinamo Tbilisi because of a foot injury and he is likely to miss Sunday's game against Swansea.
The whole Bale transfer saga has cast a long shadow over Tottenham's summer, but Sigurdsson says the squad have carried on as normal in spite of the speculation.
"I think we've dealt with (the Bale situation) quite well," the 23-year-old added.
"The club has dealt with it really well as well. Us as players, we can't really do anything. We just keep training.
"We don't really think about who is coming in or who is leaving.
"When they come in hopefully they'll fit in. But when you're at a big club like Tottenham, there is always going to be a few players coming in and a few players coming out. That's just how it is."
Sigurdsson is concentrating all his efforts on trying to achieve the top-four finish that eluded them last season.
Arsenal managed to sneak in to the Champions League ahead of Spurs for the second successive season last year, but Sigurdsson thinks the club are in a strong position this term after the summer signings of Paulinho, Soldado, Chadli and Etienne Capoue.
"We've brought in a few good players," Sigurdsson said.
"Hopefully there'll be one or two more to strengthen our squad because it's a long season, many competitions, we need a lot of good players.
"We've had a good pre season. It's been difficult for them to come in, they need to know how we play and we need to know how they play.
"A few more games and everyone will know each other a lot better."
