We now have huge belief as a side - Morgan

Eoin Morgan wants his England one-day team to keep pushing themselves to new heights and believes there is a confidence in the squad that anything is possible.

England's focus now returns to white-ball cricket with Morgan back in charge for the five ODIs against Pakistan followed by a one-off T20 which finishes the international season.

The importance given to 50-over cricket is reinforced by there being no rotation in the one-day squad for this series as eyes remain firmly fixed on the Champions Trophy next June.

Since the beginning of the last home season, England's reinvigorated one-day side has ticked up an impressive list of batting feats: a first total over 400, another total of 399, chasing down 350 with six overs to spare, a ten-wicket win chasing 255 and, individually, a record 46-ball century from Jos Buttler plus Jason Roy's 162.

Since May 1, 2015 they have scored their runs faster than any other team and hit more sixes.

"The key phrase is pushing the side. Over the last 12-18 months we've seen the progression of everyone and the skill levels," Morgan told ESPNcricinfo at a NatWest Cricket grassroots event. "There's a huge amount of belief. It's almost as though there are no restrictions to anything we can do."

However, Morgan wants more consistency from the side - series win against New Zealand, Pakistan and Sri Lanka have been tempered by losses to Australia and South Africa since the last World Cup - and a climb from their current position of No. 5 in the rankings. Within the next year, the period which includes the Champions Trophy, he wants England within the top three.

"Realistically, if we want to be favourites going into the Champions Trophy or the World Cup then we need to work our way up the rankings which means showing more consistency in all three facets. We want to be in the top three three years before the World Cup. You still need to deliver in the tournament itself, but getting the results to move up the rankings builds confidence."

Morgan believes that one of England's most significant results of late has been the tie they earned in the opening ODI against Sri Lanka at Trent Bridge when Liam Plunkett launched the final ball for six following a stand of 138 between Buttler and Chris Woakes to revive the chase.

"We were down and out," Morgan said. "It's about building the belief that no matter how far behind the game you are there is an escape route."

Morgan said he sees "17 or 18 players" that the Champions Trophy squad will come from next year in England. But he added that the squads for the tours to Bangladesh (security permitting) and India will be selected with those specific conditions in mind. He indicated four spinners could be the picked for those trips, something England have edged towards with Liam Dawson's call-up against Pakistan.

Morgan explained that, in a perfect world, he would be able to call on a left-arm quick who can bowl 90mph - that is now available in T20 with Tymal Mills, but he is not an option for 50-over cricket. However, Morgan has been delighted by the battering-ram role played by Plunkett and is excited to have Mark Wood's pace back.

"We probably have three guys who can do it [bowl at 90mph] at the moment and you want to have one in the side that can hurry up the batsmen when the ball is offering nothing else. That's important in the 50-over game where it can stand still for periods."

From a personal point of view, this series will be Morgan's return to action having been out for almost a month with a chipped bone in his finger. He led from the front in 2015 home season with prolific series against New Zealand and Australia, but has been the most underwhelming of a dazzling top order since.

He hasn't hit an international half-century in 23 innings but made an unbeaten 47 off 39 balls in the T20 against Sri Lanka, and was frustrated that the injury struck when he was finding form having made a century for Middlesex in late July.

"The finger doesn't look great but it's functioning better than it looks," he said. "I had my first hit two days ago and didn't walk out of the net thinking I'm that far behind. That was quite nice because I actually broke it when I was finding a bit of form which was a bit of a pain. I've had breaks away before, then come into series without having scored many runs, so am very relaxed and feel quite refreshed"
