Diego Costa has admitted he joined Chelsea because of the thought of working with Jose Mourinho, claiming he owes a lot to the Portuguese boss.
He left Atletico Madrid for Stamford Bridge in 2014 and won the Premier League title in his debut season in west London.
However, Mourinho’s second spell soon became one to forget just six months later as he was sacked in December 2015 with the Blues just outside of the relegation zone.
Speaking about his time with Mourinho, Costa insists the Man United coach understands how to get the best out of his players.
“In all honesty, I always tell people I am grateful to Mourinho because he helped me a lot,” he said.
“As a player when you want to improve you always look for the best coach and Mourinho is one of the best.
“I wanted to come to Chelsea because of Mourinho. When I considered Chelsea I thought about the fact that Mourinho was here.
“He is a coach that demands a lot from his players, he wants the maximum.”
Reports heavily linked him with a move to former club Atletico last summer but Antonio Conte convinced him to stay.
Just like we’ve seen at United, Mourinho has not only been able to get the best out of players already at the club, he has also been able to sign the top players around the world, even without Champions League football to offer.
