"After a successful first year with Spurs, my future was up in the air when I headed off on international duty with Scotland in September 1987," he wrote in a column for SunSport.
"There was a good chance that I'd soon be leaving White Hart Lane and I was aware Rangers and Graeme Souness were keen to sign me.
"I thought no more of it. I made it clear it was for the clubs to sort out - and only then would I get involved.
"But during the Scotland get-together, it also became apparent that I had more options that just Rangers.
"Through a third party, I was made aware that there was the option of going to Old Trafford - should I be interested.
"In the end, my heart was set on joining Gers when the time came to leave Spurs and I moved to Ibrox in October 1987.
"Do I regret not signing for United? Well, my 11 years at Rangers didn't work out badly did they?
"Coming back to Scotland was the right move for me. I was sure of that then and I've no regrets.
"It would've been an honour to play under Sir Alex at club level but it wasn't to be."
