Australia paceman Mitchell Johnson says he is not affected by the taunting he is receiving from England supporters in the Ashes series.
The 33-year-old left-armer has been the subject of a derogatory song which mocks him for bowling "left and right".
Johnson took six wickets at Lord's when Australia won by 405 runs but only four in the two Tests they have lost.
"I definitely feel like I can take the brunt of it and I take the focus away from the other guys so I've really embraced that role," he said.
Johnson was verbally taunted by England fans during the 2009 and 2010-11 series which England won, but responded with 37 wickets when the teams met in Australia in 2013-14, inspiring his side to a 5-0 whitewash.

But towards the end of his team's eight-wicket defeat against England at Edgbaston last week, Johnson stopped his run-up as he approached the wicket and then bowled from way behind the crease.
He says that was his way of responding to the taunts, rather than a sign the spectators had affected him.
"I get amongst it a bit more now," Johnson said. "When the whole crowd is cheering my name at the end of a game after (England) have just won, you have to take that as a compliment. When I stopped in my run-up, it was deliberate to try and have a bit of fun with the crowd."
Johnson took his 300th Test wicket at Edgbaston but admitted Australia bowled poorly as a unit during the defeat.
He said: "We didn't bowl in partnerships. Throughout that whole game there were moments when we bowled well but a lot of moments where we could have bowled better and bowled in partnerships.
"That's when we're playing our best cricket - when both guys are bowling well at each end."
England will be without key swing bowler James Anderson because of a side injury for the penultimate match at Trent Bridge starting on Thursday.
Johnson said: "It's a massive loss for them, they have to bring in somebody else that has to match him and that's going to be pretty difficult to do."
