Former Celtic striker says he turned down the chance to join Rangers.
Pierre van Hooijdonk says he rejected the chance to play for Rangers due to his Celtic connections.
He told the Scottish Sun he was asked to join the Gers while at Nottingham Forest in the late 90s.
He said: "Advocaat called and I spoke to him. He asked if I would come to Rangers. He told me money was no object and that I could earn a lot.
“I said to him, ‘No, Dick. You will soon witness for yourself what this means. When you take over at Rangers, you will see that this is impossible for me’. I could never have worn a Rangers strip after playing for Celtic."
Van Hooijdonk, now 45, had played for Celtic between 1995 and 1997 for two and a half-seasons.
He was unable to prevent a rampant Rangers side winning Scottish titles in this period, with Celtic only breaking the Gers' stranglehold in 97/98, the season after he left, denying their rivals a 10th title in a row.
Van Hooijdonk did manage to win the Scottish Cup with Celtic in his first season in 94/95, and went onto score 52 goals for the club.
Dick Advocaat enjoyed success despite Van Hooijdonk's snub. Rangers went onto win the next two titles in succession, the first in the SPL era.
For Celtic fans, it was probably just as well they did not have to endure this while watching a former striker of theirs rubbing it in.
