Jose Mourinho says Pedro was "not quite Maradona but close" on his Premier League debut for Chelsea against West Brom on Sunday.
The Spain international joined earlier in the week from Barcelona for Â£21.4million, but shone from the start as he scored one and assisted another in Chelsea's first victory of the season against West Brom on Sunday.
Pedro was a constant threat throughout on his Premier League debut, and Mourinho was full of praise for his new signing.

"He wasn't quite Maradona but he was close," Mourinho told Chelsea TV after the game. "He's a very good player.
"There is always a question mark because of how many top players come to England and don't perform immediately.
"We have examples in our club and there are lots of examples at other clubs, so it's very nice for him to come and straight away perform the way he did.
"I expected him to perform like that because he had a good pre-season, and he played three competitive matches. He came with minutes, with intensity, so it was not a question of intensity and condition, it was a question of understanding.
"We worked tactically every day since he arrived for him to try to understand the team and for the team to try to understand what he wants and needs. It was a very good performance."
