England captain Eoin Morgan has played down his current lack of form heading into the Cricket World Cup, claiming that he is "not really that concerned".

The 28-year-old has scored just two runs in his past four innings ahead of Saturday's opener against Australia at the MCG.

However, the left-hander says that he will take great comfort from the fact that it was not so long ago he struck a century against the tournament hosts at the same venue.

"[I'm] not really that concerned," he told reporters at this morning's press conference. "I went through a bit of a bad patch before Christmas and I feel, since I started with the Sydney Thunder at the Big Bash, I've started to turn things around.

"I've had a couple of low scores but I'll look to cash in on Saturday if I manage to get past 10-20 balls. I think it is four or five games since I scored a hundred so I don't have to look that far back to actually reconnect with what works well for me.

"I took a lot from that hundred I scored at Sydney, particularly because it was against Australia, and the first game is a big game against Australia so I'll take a lot of confidence from that game."

England suffered defeat in their final warm-up game prior to the showpiece tournament by falling to Pakistan yesterday morning.
