With the clock ticking on his remaining few months as International Olympic Committee (IOC) President, Jacques Rogge is understandably beginning to think about what his legacy will be.

It is seemingly not something that has been on his mind for all that long.

During a press conference at the inaugural Winter Youth Olympics in Innsbruck in January 2012, I asked him if he thought the Games would be his greatest legacy as IOC President given that he is considered the founder of the competition.

"A legacy is for when you are dead, and I'm not planning on that happening anytime soon," he joked.

But, when asked a similar question a few months during the London 2012 Olympics, his answer was different.

He explained just how hard he had worked, despite opposition, to set up the Youth Olympics, pointed out that the vital revenue sharing deal between the IOC and the United States Olympic Committee (USOC) was reached during his watch and that he had been a safe pair of hands.

The 71-year-old Belgian, the eighth President of the IOC, was always considered a safe option when he took over from the charismatic Juan Antonio Samaranch back in 2001.

Samaranch's name is still whispered with awe in the IOC after he took the organisation from near bankruptcy in the 1980s to huge financial prosperity by the time he handed over to Rogge.

That much was clear when I attended the unveiling of the Samaranch Memorial in Tianjin in China at the end of last month. Many IOC members were in attendance, including Rogge himself, who praised his predecessor.

Walking through the Samaranch Memorial, it was clear exactly how much the last Spaniard had contributed to the Movement and it was another clear reminder that he was by far the most important figure in the history of the Modern Olympic Games behind only its founder, Baron Pierre de Coubertin.

It clearly has an impact on Rogge, who ask, in a half-joking, half-serious way to Samaranch Memorial founder C K Wu - an IOC Executive Board member - if he would build a similar momument to him one day.

The position has aged him, which is one of the factors why he will retire as an IOC member when he steps down in September, but in terms of how he is remembered, these last few months of his reign are perhaps the most crucial to his legacy.

On July 4, the host city of the 2018 Youth Olympic Games is due to be elected in Lausanne. Buenos Aires, Glasgow and Medellín are vying for the event, and where the event will be crucial in deciding just how Rogge's pet project continues in its development.

Then, at the vital IOC Session in Buenos Aires in September, a new sport will be added for the 2020 Olympics - or the membership may decide to ignore the controversial decision of the Executive Board to axe wrestling and decide to save it, which would be a slap in the face to Rogge.
