England Test side not a finished product yet: McCullum

England Test head coach Brendon McCullum expressed satisfaction with his team's ability to soak pressure despite possessing the ability to dominate with the ball and bat.

Under McCullum and red-ball captain Ben Stokes, England have won all of the four Tests - three against New Zealand and one against India. In all those matches, they have chased totals over 250, including a record 378 in the rescheduled fifth Test at Edgbaston.

While happy with results, McCullum said that the team is not a finished product.

"We're not a finished product first and foremost," McCullum told SENZ Breakfast.

"We're a month into it and we've had some great results and we've seen the cricketing world put them on notice a little bit, but we need to ensure that this becomes a norm for us. That this style of play and what we're trying to achieve is completely authentic to us in any given situation and that will be the real challenge," he added.

England have played all their matches under McCullum at home and are scheduled to play three more against South Africa next month. They are slated to play overseas Tests only in February, 2023 against New Zealand. McCullum felt his team can adapt well to foreign conditions as well.

"Obviously conditions around the world will mean that we'll have to be relatively adaptable as well but look, I think that's one of the beauties of this group. I think there were times throughout the two series that we've played where we've had to absorb pressure as well," he said.

"Much has been made of the destruction that we were able to operate with the ball in hand particularly and our hunt for wickets with the ball, but there's times where we had to absorb pressure. When that was needed, the guys really did it, which was really satisfying too," McCullum added.

McCullum praised his players' abilities and captaincy of Ben Stokes.

"It's early days but it's certainly a nice changing room to be around; a wonderful group of guys and clearly an immense amount of talent and ability within the dressing room and really well led by the skipper in Ben Stokes too," he said.
