Eoin Morgan believes Kevin Pietersen will slot straight back into the England side when they face New Zealand in the second T20 international on Thursday night.
England lost by five runs in the opening game of the two-match series at The Oval on Tuesday, with Pietersen rested after three months out with a knee injury.
But he has been passed fit to return and Morgan, skippering the side with Stuart Broad rested ahead of the Ashes, is convinced Pietersen is back to his best after he scored an unbeaten 177 for Surrey in the County Championship.
"My role is to get him in and his role is to win the game," said Morgan.
"Kevin is a huge part of English cricket and has been for a long time. What he brings to the table probably very few people in the world can.
"He can take the game away from you at any stage and we saw during the week the way he performed, he takes a lot of pride in when he goes out there and bats.
"He looks in good form."
