Chelsea owner Todd Boehly reportedly singled out Raheem Sterling for a dressing room dressing down after the Blues' 2-1 defeat at home to Brighton last April.
The Seagulls came from behind to win at Stamford Bridge towards the end of a miserable campaign for Chelsea that saw them finish 12th in the league, and Boehly headed to see the players after the final whistle.
According to The Telegraph, Boehly gave Sterling a personal pep talk first rather than speaking to the whole squad.
The American reminded Sterling that he is a world-class player - having won four league titles at Manchester City - but demanded more from him in terms of performance and leadership.
