Cheltenham striker Jeff Goulding has branded the 2-0 defeat to Bristol Rovers last weekend as a "wake-up call".
The Robins flew through the first half of the season, defying predictions of a relegation battle to sit comfortably in the top three before Saturday's home beating.
Although the loss did not see Goulding and his team-mates drop out of the automatic promotion places, both Shrewsbury and Swindon gained ground on the Whaddon Road outfit with victories, and the forward stressed the need for the Cheltenham squad to maintain a gap between themselves and the chasing pack.
"Being a derby it was not great, but it was our first loss in 11 or 12 games," he said. "People would not have given us a hope of doing that at the beginning of the season.
"It could be just what we needed. We didn't play well against Aldershot but we managed to win and maybe it is a bit of a wake-up call.
"Now we know the chasing pack are catching up and we have to keep winning to keep them below us."
