Lambert can handle Southampton's promotion aspirations
Saints managed a seventh-placed finish last season and, having strengthened their squad over the summer, will be expected to set the pace.
Lambert, who hit 37 goals last term is refusing to set any targets.
"We're confident in our ability," he said. "Other people are putting us as favourites though, not us, so we're just concentrating on being fit for the start of the season.
"I'm not setting targets, I just want to be fit and to try to play because I know if that happens then the goals will come."
