England have some key areas to address if they are to advance to the later stages of the World Cup, according to coach Peter Moores.
The tournament began in dismal fashion for Eoin Morgan's men as they were crushed by 111 runs by co-hosts Australia in Melbourne.
They next face in-form co-hosts New Zealand in Wellington on Friday, and Moores hopes to see signs of improvement.
"If we're going to win this tournament we've got to get better over the next few weeks so by the time we get to the knockout stages we've got a real chance of putting people under pressure to win games," he told Sky Sports.
"(The defeat) showed there's a gap between us and Australia. We can still beat them, of course we can, and we've got to try and bridge that gap over the next few weeks as well as winning games.
"If we play Australia again it will be in the knockout stages and by that time we've got to have addressed some of the key areas where we need to get better."
