Pedro has reportedly decided to join Chelsea over Arsenal after speaking to former Barcelona teammate Cesc Fabregas, who has played for both London clubs.
The Spaniard returned to the Premier League last summer, joining Chelsea three years after leaving the Gunners for Camp Nou.
According to Spanish publication Sport, Pedro was worried that his lack of English would hinder a move to the Premier League, but Fabregas highlighted the number of Spanish speakers in the Chelsea dressing room to convince him to move to the champions.
The winger is thought to be considering his future after Barcelona signed Arda Turan.
