Justin Langer has leapt to the defence of Australian teammate Brett Lee after he was repeatedly taunted by England supporters in Melbourne.

Members of the Barmy Army yelled 'no ball' every time he ran in to bowl during one eight-over spell.

They're within their rights because they've paid their money but there's still some integrity in life, I think Justin Langer

Lee's bowling action has come under scrutiny in the past and the Australians did not see the funny side of the barracking.

"I thought they were a disgrace," said Langer, whose innings of 250 enabled Australia to declare on 551 for six.

"It worked in our favour. There's no better sight on a cricket field than Brett Lee or any other fast bowler running in and bowling as fast as that, it's a magnificent sight.

"If it did help to fire Brett Lee up then all the better for us."

The fans kept up a cacophony of noise

Langer also voiced fears for the integrity of cricket after England captain Nasser Hussain stood his ground in another catching controversy.

Hussain was deemed not out by the third umpire after Jason Gillespie claimed a diving catch.

Langer, who scored a double century in the match, said he felt Hussain should have walked.

"It was within the rules (Hussain standing his ground) but in an ideal world I would like to see if a player says he's out, he's out," Langer said.

"From where I was standing it looked out. It's something we have got to look at.

Gillespie's celebrations were premature

"Jason was sure he caught him and I guess it's disappointing the decision didn't go his way."

It is the second time this series Langer has called on an England batsman to believe the word of an Australian fielder.

In his exclusive BBC Sport Online column, Langer criticised Michael Vaughan for not walking in the Adelaide Test after he claimed to catch him out.

But Langer himself came in for criticism in the West Indies in 2000 when he stood his ground and survived after questioning Brian Lara's catch at slip.

The growing number of on-field disputes brings into question the use of technology in cricket.

But England coach Duncan Fletcher said he was in favour of the technology.

"The technology is there so why not use it?" Fletcher asked.

"I think Nasser proved he did the right thing by standing his ground."

The controversies took some gloss off Langer's marvellous knock.

"I am thrilled. It was nice to capitalise and get the opportunity to get a really big score.

"I really wanted to take the opportunity to nail a big one," Langer added.
