Jason Robinson has backed the Lions' tour management and players after Gavin Henson published criticism of the summer tour of New Zealand.

Wales star Henson criticises Lions coach Sir Clive Woodward's preparations and tactics in his new book.
"Sometimes, you have to bite your lip," said Robinson. "It's about pulling together to achieve a goal, and I don't think that is the best way to go.
"If you have got a problem, then go to the person and sort it out."
The Lions lost the Test series 3-0 to the All Blacks.
Robinson, a veteran of the losing 2001 Lions tour to Australia, admitted he had an advantage over some because of his years spent working under Woodward with England.
"I know a lot of the (Lions) management from previous occasions, and how they operate, so for me it was easier to deal with," he said.
"If you are not used to certain people and personalities, it can rub you up the wrong way if you let it. There will always be times when you disagree with views of certain people, but the main thing is that everyone has to do their job.
"It is a very tough job playing against New Zealand, the form team in the world, and coming together for such a short period of time was always going to be a big ask, but I felt that everyone there put everything into it."
Speaking on Monday, Lions captain Brian O'Driscoll agreed that Henson may regret taking a swipe at unnamed squad members in his book.
"I don't think you do yourself any favours by giving it out about team-mates in a book, rather than saying it to their face," he added.
"I've got some comments to make on how I thought the tour went, but none of them criticising any of my team-mates. It is more objective, the way I look at it."
O'Driscoll's own Lions recollections will be unveiled in a book published later this month.
And he did go some way to endorsing Henson's criticism of Woodward's preparations for the Test series.
"There are certain parts of his argument you could probably agree with," O'Driscoll told BBC Sport.
"I wouldn't agree totally with it all but there are aspects Clive himself would probably change if he could.
"You don't have to be brilliant to realise the Test team probably needed to play together a bit more often."
Lions chief executive, John Feehan, has indicated Henson is unlikely to face disciplinary action despite breaching a gagging order, which does not expire until next week.
Players were not supposed to criticise aspects of the tour for a period of 100 days after it ended.
