Don't rely on Bopara for the Ashes - Warne

Three Test centuries in a row from Ravi Bopara did not impress Shane Warne, who doesn't think the allrounder is good enough for the international arena. Bopara starred against West Indies in his previous three matches, including two hundreds at No. 3, but Warne doubts his temperament.

"Bopara is a good first-class cricketer, but he is not an international cricketer,'' Warne told the Daily Mirror. "I think he's got all the talent in the world, but I just don't think he's got the temperament.

"He can be put off his game too easily and he's too worried about how he looks. Let's hope England aren't relying on Bopara [for the Ashes] because they could be in trouble.''

Warne said Kevin Pietersen, who has been struggling with an Achilles problem, and the captain Andrew Strauss would be the keys to an England success. "Paul Collingwood can be good, but he has to be batting with someone like Kevin Pietersen to bring the best out of him,'' Warne said. "For England to succeed they will have to bat around Pietersen and the captain.''

Australia are preparing for their first tour game in Sussex on Wednesday, which will be followed by a match against England Lions in Worcester. The first Test is in Cardiff on July 8.
