Andre Villas-Boas considers Chelsea captain John Terry to be one of the best central defenders to have ever played the game.
Terry has won three Barclays Premier League titles and four FA Cups during a Chelsea career spanning 515 games and is the most successful skipper in the history of the club.
The 31-year-old also has 71 caps for England, and is currently the captain of his country, although his suitability for the role has been called into question.
Terry lost the armband in 2010 after allegations of an affair and, since being reinstated as captain, has been charged with racially abusing Queens Park Rangers's Anton Ferdinand.
Villas-Boas, though, says Terry's on-field abilities can never be questioned, and the the defender is one of the greatest centre-backs of all time.
"His qualities are amazing and he's a player who almost guarantees you success in terms of individual and collective performances.
"He is a player we hold in the highest esteem and a person I have great empathy with and great respect for. Whichever route our lives will take, JT is a person I will always hold as a friend.
"As a player he has been extremely successful in the world game. He was involved in my knowledge-making and in my progress as a manager."
Terry will appear at Westminster Magistrates Court this week to answer the charges of the incident involving Ferdinand, which took place at Loftus Road in October.
The duo came face to face again on Saturday as Chelsea triumphed 1-0 against QPR in the fourth round of the FA Cup.
