Gillingham manager Justin Edinburgh has admitted he is surprised by their fine start to the League One season.
The Gills are two points clear at the top of the table, having won four of their last five league games.
"We are massively overachieving and there is no doubt about that," he told BBC Radio Kent.
"We are not big-hitters in the league financially but that doesn't say we can't continue to develop and fight to stay up the top."
Edinburgh was appointed Gillingham manager in February and led the club to a 12th-placed finish last season, seven points outside the play-offs.
The former Tottenham defender made six permanent signings over the summer but is confident his young side, who are yet to be beaten at Priestfield this campaign, can improve further.
"They are not the finished article. Their age and appearances under their belts tell you that," the 45-year-old added.
"We are learning a lot about ourselves and will continue to do so.
"We've shown lots of positives but I just feel that we have got to be able to embrace the position we are in.
"We need to try and take the level of performance up.
"We are at the top and people will want to come and beat us. We have got to deal with that expectation."
