Terry told Marca that he and midfielder Frank Lampard regularly keep in touch with Mourinho.
"We send each other text messages and often wish each other good luck,'' Terry said. "He's interested in our results and everything that happens at the club.
''He's not only in contact with me but also with Lampard and other players.
"Mourinho has a great relationship with our fans because we won the Premier League and several other titles with him.
"Real Madrid must be respected, as he is under contract. The fans have clearly shown that he is the man they want after everything he won. He's still 'The Special One'.
"He's a top manager who I really enjoyed working under."
