Spinner Graeme Swann has told England not to get carried away by their new world number one Test ranking - and instead focus on completing a 4-0 series victory over India.
Andrew Strauss' men confirmed their new status by thrashing the tourists by an innings and 242 runs on Saturday.
"We said before the series it didn't matter if we got to number one in the world," said Swann.
"It's about finishing the series well and that is what we are aiming to do."
Swann, who is currently ranked fifth in the world Test bowling rankings, took two wickets in third Test victory over India and is keen for England to round off their sixth consecutive Test series victory with another win at the Oval.
"It's the last Test match for a while and it's a good chance for us to sign off on a winning note," added Swann.
"We have played some exceptional cricket in the last 18-24 months and it would be a shame if we ruined it all by cruising through this game so let's make it a really good five days and see what happens.
"(Coach) Andy Flower and Andrew Strauss won't be allowing us to rest on our laurels and just glide through this game. They will be keener than ever for us to give 100%.
"It wouldn't be much of a team if we just fell to pieces and threw it all away."
The tourists have been completed outplayed in the last three Tests. However Swann has refused to underestimate the former world ranking leaders ahead of the Test on Thursday.
"The best thing we have done all series is keep India below 300 each time we have bowled and we need to try and keep that up.
"Cricket is one of those games when if one team is on top the other can look as though it is being dragged through the mill so it would be very dangerous to assume this Indian team is anything other than a world-class outfit and we will have to play exceptionally well to match them."
