The UEFA Champions League is definitely one of the toughest club competitions in world football. Top clubs from top leagues compete in one league in order to be crowned as the best team in Europe.
With such a high level of competition, it is almost impossible to think of scoring a hat-trick in this tournament where every opposition is a proven contender in their domestic leagues.
However, some legends have defied that logic and have not only scored hat-tricks for one club, but also went on to do the same for other clubs in the same competition too.
Here are nine such greats of the game.....
