Batting legend Hussey says Lehmann – known as ‘Boof’ — has the personality to restore some sanity before the Ashes series begins in 15 days’ time.
Lehmann was installed on Monday when Cricket Australia sensationally sacked Mickey Arthur after a string of poor results and breaches of discipline.
Hussey said: “Like most people, I was very shocked.
“The toughest thing for the team is going to be to put all this behind them. Playing international cricket, let alone an Ashes series, is extremely tough and you need to be 100 per cent focused.
“It doesn’t help to have all these distractions and it will be tough for the inexperienced players.
“But the decision was made swiftly so hopefully the guys can concentrate properly on preparing for the Ashes.
“I really think Boof can galvanise the team. He is a very level-headed guy, he’s got a great understanding of the game and knows how good teams work.
"I’m very confident he can come in and have an immediate impact.”
Lehmann has already hinted that he wants to utilise the skills and knowledge of former players such as Shane Warne.
And ‘Mr.Cricket’ Hussey, speaking to promote Sky Sports’ covering of the Ashes, is offering his services.
He said: “I’d certainly be willing to help out if they want me to, for sure. Michael Clarke, the captain, wants to do that sort of thing – whenever we’ve been playing in Australia, he always invited a couple of past players to the training sessions.
“I found it invaluable to learn a few lessons from their experience, trying to pick up a tip or two.”
