Pinning high expectations on particular atheletes can often result in disappointing performances for spectators, a local newspaper says.

A commentary in the English language newspaper China Daily says that people differ in their expectations of the Olympic competitions. Some are obsessed with their favorite athletes and become excited even at the sight of their icons. They expect their beloved athletes to remain young and energetic forever. The media largely focus attention on the medal hopefuls. But the most impressive performances are always those of the unexpected medalists.

It adds unexpected factors affect athletes' performances, and such factors don't always meet spectators' expectations. Few athletes come to the Olympics without cherishing the hope of winning a medal, but anything can happen in a competition.

Therefore, the paper points out that the degree of unpredictability adds to the charm of sports competitions and makes the Olympics attractive to sport fans all over the world.
