Diego Costa has revealed that outside Chelsea, Manchester City striker Sergio Aguero is the most skilful Premier League player he has played with in his career.

Aguero and Costa both played for Atletico Madrid in La Liga and the Brazil-born attacker says the Argentina international possesses a sublime set of skills.

"I had the opportunity to play with Sergio Aguero at Atletico so I would have to say him, he's a very skilful player," Costa told the club's official website.

Regarding the best skills he has seen live on a football pitch, Costa recalls a certain Brazilian great who plied his trade for such clubs as Barcelona, Paris Saint-Germain and AC Milan.

"There are so many fantastic players who have the ability to do things in every game, but some of the skills Ronaldinho did were absolutely incredible, unbelievable," Costa added.
