"That's something that potentially could be looked at. Everything else in the game has changed."

Despite Friday's 13-run defeat at The Oval, Morgan said he was proud of his team's effort.

"The way we went about the chase, all credit goes to the guys. It's not a bad day for us, it's a continuation of the way we want to play," English skipper said.

"The guys were willing to take 398 on, throw themselves at it and have the ability to throw themselves at it. It was very entertaining," Morgan said.

New Zealand captain Brendon McCullum also acknowledged England's dramatic improvement since their dismal displays at the World Cup.

"This England team are playing a completely different brand of cricket to what they've played in recent times. Both teams put up a hell of a fight and neither team probably deserved to lose," McCullum said.
