The 4-0 defeat in Kent stretched the Hornets winless run in 2013 to 13 matches, and with bottom of the table Three Bridges winning again, 2-0 at Tooting & Mitcham, the gap has been cut to just three points.
“Now we are (in a relegation fight),” Colbran said. “I never dreamed we would be in this position when we were 11th in the table but I don’t think we’ve won since then.
“But we are where we are and we have to deal with it and get ourselves out of it. I’m a fighter and I’m not giving up and the players won’t give up either, we’ll be doing everything we can to make sure this club stays up.
“Apart from the last 20 minutes on Saturday the players have given their all and got only a point, we have got to start scoring goals.”
And Colbran blamed poor finishing again as his side missed a number of good chances in a strong first half performance. The Rams went ahead shortly before half-time, but even at 1-0 down the visitors spurned opportunities.
“If we’d finished all our chances in games we wouldn’t be sitting where we are in the league,” Colbran said. “We started quickly as we always seem to do, created early chances but again didn’t put them away so we’re up against it from there.
“When you lose 4-0 people blame the defence but if we’d taken our early chances there’s no way we’re conceding four goals.”
Horsham do have three games in hand on their Crawley-based rivals Bridges, and one in hand over Walton Casuals who are two points behind in second-bottom. But Colbran’s side are yet to win this year and face a tough final ten games, starting on Tuesday night at home to title-chasing Dulwich Hamlet, weather permitting.
