Chelsea winger Pedro says he was surprised by the warm welcome he received from boss Jose Mourinho.
The former Barcelona man snubbed a move to Manchester United to move to Stamford Bridge after he was convinced by the Portuguese and Spain team-mate Cesc Fabregas.
He scored on his debut game against West Bromwich Albion where he also provided an assist to striker Diego Costa.
"He is very different face-to-face," he told Marca.
"He treats you like one of his family. He values and respects his players and demands much from them.
"It was very hard to leave Barcelona and I will never celebrate a goal against them, because the club gave me everything."
