Many who? Who felt/feels Trankov is the best? If those who matter did, i.e. the Russian fed, they would have broken up the pair and found Trankov another partner. Trankov doesn't like Maria that much to refuse to work with anyone else but her.
Tatiana is not polished. She looks a bit trashy and yes, I'm watching the same person. Who said Tatiana and Aliona are by far the best two female pairs skaters in the world? When and where did they say it? German newspaper?
