Jonathan Trott feels the special tradition of Ashes matches will be diluted if contests between England and Australia continue to spill outside the regular tours.
Australia arrive in the UK tomorrow for a five-match ODI series with England, starting on June 29. Trott warned against scheduling series outside Ashes years to protect the England-Australia rivalry.
"It definitely needs looking after," Trott told the Evening Standard. "It mustn't be overdone. You want it to be special. England used to play Australia at home every four years, it was in the books and people had years to look forward to it. Now, they were here two years ago, they're here now and they're here again next summer."
