Theophile-Catherine leaves Cardiff City to join Saint Etienne
Cardiff City defender Kevin Theophile-Catherine has joined Saint Etienne on a three-year deal.
The 25-year-old French defender spent last season on loan at the Ligue One side and became a regular, playing 42 games for the French club.
Theophile-Catherine joined Cardiff from Rennes for £2.1m in August 2013 on a four-year deal.
"We're very pleased to have reached an agreement with Cardiff," said Saint Etienne president Roland Romeyer.
"Given the standard of his performances, the option to buy was a priority for us and his versatility is a valuable asset to the team."
Reports in the French press say Saint Etienne have paid euros 2m (£1.45m) for Theophile-Catherine.
