Shane Warne has expressed his worries with the Australian Ashes squad which includes five potential opening batsmen.
Warne took 708 Test wickets in his career, including 129 in England but it is the opening spot that he is most worried about.
Shane Watson, David Warner, Ed Cowan, Chris Rogers and Phillip Hughes have all been picked in the 16-man touring party for the Ashes which start on July 10.
Warne told BBC Radio 5 Live: "It appears they don't know their best team. By picking all those openers, it seems they don't know the right mix."
This comes as Australia attempt to secure their first Test series win on English soil since 2001, and it will be their second away Ashes series without Warne.
Australia are already in England ahead of the ICC Champions Trophy and were dismissed for 65 in their second warm up match against India yesterday. In their first, they beat the West Indies by four wickets.
"I've been frustrated with the selections for the past 12 to 18 months", Warne added. They've picked players that have not performed well at first-class level, at international level.
"There are wonderful young players and good players that have not been selected."
Australia are currently ranked fourth in the Test rankings, and have beaten England only once in their past four series.
England lie in second spot in the rankings, with India splitting them from the Aussies. South Africa currently top the ranks.
