The former 'Gers midfielder says his good mate Whittaker doesn't need the money being offered to him by Bursa and is supremely confident he will remain at Ibrox despite having the chance to join Kenny Miller in Turkey.
"I've not spoken to Steven about it, but I do almost find the Bursaspor thing laughable," Thomson said.
"They are throwing life-changing money around, there's no question of that.
"Whitty's a wealthy enough boy already I'm sure.
"I don't think anyone will push him about just because of money.
"He's a top player who is motivated by playing on the big stage and winning trophies. I'm not sure an extra few quid in Turkey would decide it for him.
"It's not for everyone. I think he'll look at maybe Kenny Miller and Kris Boyd and realise things don't always work out when you leave Rangers. It's hard to leave a big club like that. The fans are second to none and you need to look hard to replicate that experience.
"Some boys can move to teams in the lower end of the Premier League in England and still feel a difference.
"Wherever Whitty moved to he'd be a success but I'm pretty sure he'll stay and keep getting trophies at Ibrox.
"If I was a betting man I'd say he'd be at Rangers for the majority of his career."
