Neil Collins believes Sheffield United will only improve as the season goes on, having won once and drawn twice so far.
The defender has helped the League One promotion favourites stay unbeaten after three games and Collins is now aiming to turn the draws into victories.
"We have only conceded two goals in three league games to date, but that has included two draws so it is a positive and a negative, in that respect," he told the club's official website.
"Clean sheets are what we are aiming for but the defence is a new team within a team and we can take plenty of heart from our early season form.
"It takes time for a defence to gel, but I am sure we will get better and better."
