Keane saw his side concede in stoppage-time for the second time in five days at Barnsley on Saturday as a 2-1 defeat at Oakwell left them without a win in their first 11 league games.
Trotter said: "We are in a relegation battle.
"We are bottom of the league, with just five points. There's no getting away from where we are, and you can't say that we are in a false position, because we've not won any games.
"You can't just have two months of bad luck.
"We have the quality to get out of it. I think we're a good team but we're not earning the points at the moment."
