Heikki Kovalainen has decided against teaming up with Michael Schumacher’s former fitness guru.
The Finn has been looking for a new trainer after splitting with regular physio Petri Lehikoinen.
Reports in March said Schumacher, who worked with the Indian at Ferrari for years, recommended Balbir Singh.
Singh’s last job in F1 was alongside Giancarlo Fisichella at Force India, and Kovalainen met him for the first time at a pre-season test.
But Finnish newspaper Turun Sanomat reports from Turkey that Kovalainen in fact selected a British trainer, Dan Williams.
"His (Singh’s) methods are totally different and holistic, which I am not accustomed to," said Kovalainen.
The Team Lotus driver said Williams has worked with racing drivers before, but never in F1.
