Pedro has revealed that a phone call from his international team-mate Cesc Fabregas helped convince him to swap Barcelona for Chelsea.
The Blues midfielder, who completed the same switch one year earlier, made the initial contact on behalf of his club with the deal eventually being announced just two days later.
Having been widely expected to join Manchester United, the sight of Pedro in a Chelsea shirt came as a shock to most Premier League fans.

Pedro admits that Fabregas, along with Jose Mourinho, played a key role in his eventual decision to complete a €30million move to the west London club.
"My transfer to Chelsea was done within a couple of days. It all started with a call from Cesc," Pedro told El Pais.
"Mourinho then gave me a call and that helped me make a decision. Mourinho made me feel important and gave me confidence."
Pedro had spent his entire professional career at the Nou Camp, originally emerging from the famous La Masia academy to play for both Barcelona C and Barcelona B before taking his place in the first-team in 2008.
"We have achieved a lot together, played many important games and scored many goals. I will definitely miss Leo"
His list of honours runs longer than the vast majority of footballers, including five La Liga championships, three Copa del Rey titles and a further three Champions League titles.
Unsurprisingly, Pedro admits that he will miss life at Barcelona and is particularly sad to leave his long-time team-mate Leo Messi behind.
He said: "Messi is an amazing team-mate. He really is a great guy," he added.
"We have achieved a lot together, played many important games and scored many goals. I will definitely miss Leo.
"I will continue to see Jordi Alba, Sergio Busquets and Andres Iniesta with the national team, but I will clearly miss Messi."
