Mathilde Froustey, Sujet from 2005 till 2013 left the Paris Opera Ballet in July 2013 and joined the San Francisco Ballet as a principal dancer because there was no chance for her becoming eventually Danseuse étoile (principal dancer) in this company [REF].
Yet Sylvie Guillem, being principal dancer since 1984, left the company in 1989 at the age of 24 because she wanted more freedom, the right to perform with other companies, an arrangement the management of the Paris Opera Ballet declined [REF].
