England coach Peter Moores refused to be drawn into the debate generated by his predecessor Duncan Fletcher's recently-published book.
Fletcher - England's coach for eight years before Moores took over at the start of last summer - has been criticised in some quarters for revealing that Andrew Flintoff arrived drunk at a training session during last winter's Ashes tour.
Flintoff was subsequently stripped of the vice captaincy at the World Cup following another alcohol-fuelled incident involving a late-night trip to sea in a pedalo.
The Lancastrian all-rounder featured under Moores during the one-day series at the end of last summer and the World Twenty20 in South Africa, but is now out until next summer after undergoing a fourth operation on his ankle.
"To be fair to Freddie he's been great," said Moores. "He's got stuck in and done his work.
"He went to the Twenty20 World Cup and had some pain but managed it well. Now he is very committed to getting stuck into his rehab, to get that sorted, and get back fit.
"He's done it right and done it hard, so I look that way.
"I think Freddie is very clear on what he wants to do and is focused on getting himself back fit."
On Fletcher's book, Moores added: "I haven't read much of it. I'll probably be tempted to at some stage.
"I saw one piece in one paper and it's not for me to comment. Duncan's done his stuff and written his book and that's his choice. He was in there and I can't really comment."
Harmison winning fitness race
Moores also revealed he is hopeful that Steve Harmison will be fit for the upcoming Tests in Sri Lanka.
Harmison - who underwent a hernia operation in June - is currently playing domestic cricket in South Africa for the Highveld Lions and Moores has received encouraging reports on his condition from bowling coach Ottis Gibson.
"The first thing was to get him out there and get him fit. He played a game on Sunday and came through that OK.
"The reports back from Ottis are he's fine. He'll have two first-class games and we'll see how he goes. He's not just got to be physically fit, he's got to be bowling fit.
"We've got a couple of weeks when we get there but it's going to be crucial we hit that series very well.
"Steve's got the task of not only being fit enough to bowl but also to bowl well enough and get some form into him.
"Steve is not daft and knows not bowled for a long time but he loves bowling. He knows if he goes out there and plays a couple of games and does well he will go to Sri Lanka with confidence.
"It suits him, makes sense to go out there ad get some cricket."
