Doha: Czech tennis stars Karolina and Kristyna Pliskova are identical twins, and people are generally confused when it comes to identifying them. Karolina is currently World No. 3, while Kristyna, who is two minutes older to Karolina, is ranked No. 55. Worse still, when both sisters are participating in the same event, the mix-up between the twins becomes even more complicated. While this mix-up can seem funny to outsiders, Karolina says she's fed up of people mistaking her for Kristyna.
