Chelsea striker Diego Costa has paid tribute to Manchester City ace Sergio Aguero.
Costa found himself behind Aguero in the pecking order at Atletico Madrid.
He recalled to the Sunday Mirror: "I knew when he was at Atletico, Sergio was God. You knew what a great player he was.
"The truth was I learned a lot with him - but now, we'll see who comes out on top.
"I loved watching Sergio. He is, for me, the best I saw play - certainly the best as a team-mate.
"I enjoyed it a lot to play with him. For me, he's a great. He's one of the absolutely top-level forwards around."
