Fabio Capello has thanked his former England players in a note and wished them the best for the future, but did not elaborate on his decision to quit as England coach.
Capello resigned on Wednesday, angry at a decision by the Football Association to strip John Terry of the England captaincy.
In a note reported by Italian news agency ANSA, Capello says, "I want to thank the players, the staff and the Football Association for the professionalism they have showed me in my years as national coach."
Capello, who spent four years in charge of England, adds that he wants to say "a special goodbye to all the fans who always supported the team and my work. I wish they can all attain the highest sporting goals."
Capello flew back to Italy on Thursday.
