Remembering Manny Pacquiao's best fights

— -- MEXICO CITY -- The number of Manny Pacquiao's top fights should include at least 10 or 15, but to highlight five of his best nights in the ring, we should mention some that not only left a mark on fight night but also those that boxing fans will remember forever.

ESPN selected Pacquiao as the second-best pound-for-pound fighter of the last 25 years, and that is due to his victories against the best boxers in eight different divisions, having reached the top of the boxing sport and being considered the world's No. 1 fighter in the pound-for-pound rankings for a considerable amount of time.

Entering his 67th bout as a professional fighter -- against welterweight titleholder Jessie Vargas on Nov. 5 at the Thomas & Mack Center in Las Vegas -- it is worth recalling some of those memorable chapters of his Hall of Fame career.
