Dean Smith has admitted it has been difficult to put his finger on the reasons behind Brentford's shaky start to the league campaign.
The Bees are bottom of the Championship, picking up just one point in four games although their overall play has deserved better.
The west Londoners have taken the most shots (75) and had the most on target (30) but have ended up with just five goals, which is around the average goals scored per team.
The Bees have conceded the most goals, which is surprising as they have faced relatively few shots on goal with 34. Middlesbrough have faced the fewest on 31.
19 of those efforts have been on target, which is the worst ratio in the division with more than one in two efforts being on target.
Opponents have needed less than four shots to score past Dan Bentley, while Preston at the other end of the scale, have conceded one from 40.
The Bees head coach, though, believes these outlying statistics will even out over the course of the season.
Smith said: “It's hard to put your finger on it. We've probably not scored enough when we've been on top.
“Some teams have scored some really good goals against us. Defensively, we've conceded less chances this season against us and would be in the top five in least chances against us. Defensively, we've been really good.”
He added: “I'm sure it will (change). The players are very confident in what we do. We feel we've got better defensively as a team and the quality of our play has been the same; we just haven't taken our chances.”
