Chelsea boss Jose Mourinho has likened Pedro to Diego Maradona after his goalscoring debut.
Pedro scored the opener and set up Diego Costa for Chelsea's second in the Blues' 3-2 win at West Brom.
Mourinho told Chelsea TV: "He wasn't quite Maradona but he was close.
"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."
