During a discussion on TV commentary for the third ODI between Ravi Shastri and Kevin Pietersen, it was claimed that, with the exception of Joe Root, England had not netted during the ODI series. England had trained before the first ODI in Nagpur, but opted not to do so ahead of the second and third games in Cuttack and Ahmedabad.

With the Champions Trophy looming, a 142-run defeat in the final game saw England go down 3-0 in the ODIs, having previously been beaten 4-1 during the T20I leg.

"Firstly, it's factually incorrect, the whole statement that we don't train," McCullum told talkSPORT after the third ODI. "We've trained plenty right throughout, guys have come from a lot of cricket as well. I think it's an easy thing to have as a throwaway line that guys don't train enough when the results aren't right.

"But we've got a style and a method that we believe in. We've got guys who are battling injuries and trying to make sure that we've got enough bodies out on the field, knowing that we've got a huge assignment coming up in a week or two. Ultimately it's factually incorrect what's been said and we'll stay true to what we believe in."

"We've had a reasonably long tour, a few long travel days," Buttler said. "There have been a couple of times we have not trained but we have done plenty of training throughout the tour. We try to create a really good environment but don't mistake that for a lazy environment or lack of effort. The guys are desperate to perform and do well and improve."

McCullum only took on the role of white-ball head coach in January, having previously had sole responsibility for the Test side, and said that the tour had provided valuable lessons ahead of the Champions Trophy, which gets underway in Pakistan next week.

"I've learned a lot," McCullum said. "There's guys in our team who are incredibly talented, if we can add a little bit of craft and give ourselves a bit of confidence within the dressing room, which is ultimately the task of us as coaches, then we'll see some of that talent will flourish. It's been a good tour, so much good will come from it, albeit the results are very disappointing. But that's the nature sometimes when you come up against a very good side in their own conditions.

"Ultimately you're judged on results," he added. "From our point of view, we've got to strip away the fear of failure that results can bring. Guys are fiercely determined and competitive... how do you allow an environment to provide the freedom and clarity of thought to go out there and allow your talent to come out?

"That's what we're trying to do in the group we're building and that's what we'll try and do over the next week as well, give the guys a freshen-up in Abu Dhabi, make sure all the bodies are fit and ready to go, we've got a full squad to pick from come that first game against Australia. We do that, hopefully we walk a little taller and play a little better and end up getting better results as well."
