Chelsea boss Jose Mourinho has revealed that new signing Pedro worked hard every day since joining the club in order to be ready for the away game against West Bromwich Albion.
The Spain international stole the show on Sunday afternoon after scoring the first goal of the match and setting up Diego Costa for the second moments later.
He was called a "hero" by Chelsea fans on Twitter as he helped his new team to register their first Premier League win of the season.
"We deserved it, it was difficult but we deserved it," Mourinho told reporters.
"3-1 was short with 11 against 11, and with the chances we created, the space we found, and the way we attacked their defensive line.
"Then with one player less - we are getting experience of that - we adapted well but they scored to make it 3-2. We had the best chances to score the next goal.
"I'm happy we controlled the game well, and I'm happy with the spirit because the players really wanted to win.
"[Pedro?] 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 understand the team and for the team to try to understand what he wants and needs. It was a very good performance."
