Peter Moores has claimed that England must review their bowling tactics following the defeat to Australia on the opening day of the World Cup.
Australia managed to score 105 from the final 10 overs in Adelaide to set up a comfortable 111-run victory in the Pool B fixture, and Moores admits that the quality of bowling at the death is a concern for his side.
"It's something we will definitely review," the head coach told BBC Sport. "If we can get that area better it's going to make a significant difference.
"We didn't get it right at the end of the innings. The yorker is a very good ball at the end of the innings and some players are better at doing it than others.
"It's something we're working very hard to get better at as quick as we can. We didn't win or lose the trophy but we've got to win enough games to get through to the knock-out games and by that stage be playing well enough to beat any side."
England meet New Zealand in their second game on Friday.
