THE Reds' four-match unbeaten run came to an end on Saturday after a Scott Wiseman own goal condemned them to a 1-0 defeat at the hands of Millwall.
The defender, who made his international debut with Gibraltar on Tuesday, headed Liam Feeney's cross into his own net in the 75th minute.
David Flitcroft's side came back into the match with Marcus Pedersen and Jacob Mellis threatening David Forde in the Millwall goal.
The Reds pushed for an equaliser but defeat means they have made their worst start to a season since 1973 and remain in the relegation zone with 11 points from 16 matches.
"I'm baffled how we haven't got something out of that game," said Flicker.
"It's disappointing as we had several great chances but I still think we didn't test their goalkeeper enough.
"Defensively we were excellent. They never looked like scoring - we dominated."
Next up for the Reds is Birmingham. The fellow strugglers visit Oakwell on November 30.
