Pedro says he is a happier and more confident person after his transfer-window move from Barcelona to Chelsea.
"When someone gets to play, they gain rhythm, confidence, you're happier, you try out more things," Pedro said on the Spain national team's website. "Leaving Barca was tough for me but I'm happy with the change."
Pedro said his fellow-Spain players at Chelsea, including former Barcelona team-mate Cesc Fabregas, Diego Costa and Cesar Azpilicueta, had helped him adjust quickly to life in the Premier League.
"They've been a great support to me," he said. "The adaptation has been quicker given I already knew them from here and they've treated me very well in the dressing room, showing me how the club works."
