"Captaincy is not a burden for me. I am absolutely clear in my mind that I have to perform as a player, regardless of whether I am captain or not," the stand-in captain said.
The Nawab of Najafgarh followed up his miserable aggregate of 95 runs in the Test series with a pathetic 73 in the four ODIs against Andrew Flintoff's team, prompting questions to be raised about his place in the team.
Sehwag said with the series already decided, the Indians would prefer to rest a couple of players and give opportunity to some young guns in the side.
However, he said the final XI would be decided in a team meeting later in the evening and made public only on the morning of the match.
He also hinted that young middle order bat Venugopala Rao might take the field on Sunday.
"Venugopala Rao has been in the side before Robin Utthapa and he should be given a chance first," he said.
"Everybody will get an equal opportunity in the coming matches. But at the same time I want to stress that our primary aim is to win the remaining matches," he said.
