England batsman Paul Collingwood has questioned whether coach Duncan Fletcher was right to stand down.

Fletcher will end his eight-year reign after Saturday's World Cup match against the West Indies in Barbados.

"I am not sure whether the time really was right for him to go," Collingwood told BBC Sport.

"Fletch has continued to change his techniques. He is constantly looking at new ideas. He is a very good coach, who put his heart and soul into the job."

England captain Michael Vaughan said on Friday the time was right for a new voice.

But Collingwood, who has been tipped as a possible future one-day captain of the national side, believes the players have let Fletcher down during the Ashes whitewash and the World Cup.

"Obviously results have not gone our way this winter but our individual performances have been poor," he wrote in his website column.

"Fletch has done everything in his powers for us to perform at a high level. To go out on the note he has is very disappointing - after so much success he didn't deserve it."

Moores, who has coached the England A side since 2001, takes over from Fletcher on 1 May, with a Test series against West Indies beginning 16 days later.

"I have not worked with Peter Moores before but people who have spent time with him at the National Academy say he is very good so I am looking forward to it," said Collingwood.

"There will probably be a lot more change in store for the team, with a new coach bringing in different ideas. I think the [backroom] personnel will change as well.
