, Pienaar says he's gotten over that disappointment.
"Why regret stuff? It's something I always debate but life moves on and you have to make the best of the hand you've been dealt," said Pienaar, who captained the Springboks in all 29 Tests he played.
Pienaar, now 53, said it was tough adapting to life at Saracens in the early days of the professional era.
"Leaving South Africa and arriving at Saracens, then still very amateur, weren't ideal - I almost came back. But I was appointed player/coach and we were fortunate to win a title that year, for the first time in 127 years.
"So, when the Lions came to South Africa in 1997, I brought my friends from England with me, to come and watch.
"We toured South Africa as Springbok fans with some of our English friends, including Saracens backer Nigel Wray and his whole family. The result wasn't great, but we had a great time."
The Lions are slated tour South Africa next year and Pienaar said he would look to attend matches around the country.
"The Lions experience is just phenomenal - the camaraderie that brings together players who are used to fighting each other but then become one, they sing each other's songs, enjoy the tour together... it is just special.
"And next year's tour is going to be fantastic. We've already discussed with friends to do something special, to again tour our country and follow the Lions as they face the Springboks - I'm looking forward to being a tourist again."
The Lions last toured South Africa in 2009 when the Springboks ran out 2-1 series victors.
