Despite dropping four points at home to Ukraine and away in Poland, Roy Hodgson has no intention of changing his philosophy with the England team, or making any wholesale changes.
England will almost certainly lose top spot next month to Montenegro after their victory over Ukraine in Kiev in midweek, and in a tight group sloppy performances must be kept to a minimum.
Hodgson admitted that his side did not perform to their potential against Poland, but feels that with four sides potentially vying for one automatic qualification spot, his side will improve.
"It is going to be a tight group," Hodgson said.
"The fact is we know all matches in this group are going to be tough ones. Montenegro have already shown that because they weren't being touted as favourites beforehand.
"We know there is work to be done.
"I'm not prepared now, because we didn't do quite so well against Poland, to suddenly start saying 'we need radical improvements'.
"We need to keep working on our game and make sure we don't lose some of these important qualities which saw us get out of the group in the Euros without playing brilliantly well."
England face Sweden in a friendly next month, whilst Montenegro host San Marino.
