Jose Mourinho has admitted he was blind to Diego Costa's talent after turning down the chance to sign him eight years ago.
Costa linked up with the Chelsea manager at Stamford Bridge this summer, costing Chelsea a reported £32 million. His transfer fee rocketed last season after he lead the line for Atletico Madrid in a title winning campaign.
Blind to his talent
However, Mourinho could have saved Chelsea owner Roman Abramovich a lot of money if he had realised how talented Costa was eight years ago. Mourinho was enjoying his successful first stint as manager of the Blues, but rejected the chance to sign the then 17-year-old prospect.
The Special One admitted to a rare error in judgement, saying he did not see Costa as a potential star when he was plying his trade for Braga.
"To be fair when he was in Portugal I had a look at him, so everybody was blind, including myself," Mourinho told reporters.
A Premier League star
Now Costa has finally arrived in west London, Mourinho believes he can translate his excellent goal scoring record in La Liga to the Premier League. The Portuguese also believes Costa has the mentality to keep his feet on the ground.
"He can be [a star], yes I know,” Mourinho said. "He's still the guy that comes from a very small village behind the sunset.
"His village is behind the sunset - you want to arrive there, and it's difficult to arrive. He's still that guy.
"He's still that guy, the way he behaves, the way he acts, the way he interacts, he's still that naive, pure, simple, humble guy."
