Australian cricket captain Michael Clarke has hit a psychological barrier, according to Ian Healy and Allan Lamb.

The Australian batsman has been struggling with his performances lately, raising questions about his captaincy.

Speaking on Graeme Swann's Ashes roadshow, Healy said: "I think it's a psychological thing he's got to get over. He's gotta get out there and do his job. He used to take that for granted and now it's not happening."

"You don't think about failure as well. You go out and play. As soon as you start worry about your technique - you're gone," Lamb added,

"You've got to go out, enjoy it and play as best you can."
