England captain Alastair Cook has broken his silence after revelations from Kevin Pietersen's autobiography to say the resulting furore has "tarnished" the successful era of captain Andrew Strauss and coach Andy Flower.
Pietersen's book KP: The Autobiography was released last week and the former England batsman, who was sacked amid huge controversy in February, made several media appearances following the expiry of a confidentiality agreement with the England and Wales Cricket Board.
In the book he alleged the England dressing-room was beset by a culture of bullying and he reserved special condemnation for Flower and the wicketkeeper and former vice-captain Matt Prior.
Yesterday Cook told the BBC: "I am very proud of the era I have played in.
"To play under Andrew Strauss, to have played under Andy Flower as coach, I have only got respect for these guys," he added. "I do believe that era has been tarnished, and I am sad about that."
