Guernsey FC manager Tony Vance is trying to temper expectations after their ninth game without defeat.
The Green Lions beat Whyteleafe 2-1 thanks to Ross Allen's 88th-minute winner to stay third in the Isthmian League Division One South.
"There are positive comments going around everywhere, which is good, and the lads have earned that," he said.
"But we're only third in January, we could have three or four injuries and we're back where we started."
Guernsey, who have won seven of their last nine games, got off to a great start when Craig Young opened the scoring after 18 minutes.
The visitors hit back just before half-time, but Allen had the final say.
Vance said it is important his side keeps their good form going, as they prepare to face play-off rivals Hastings United next week.
"For me it's all about being in the mix come the end of the season and we've got top pick games off," he told BBC Radio Guernsey.
"Home games are so important to us so we've got to win those games and that's why it was really pleasing to get that win today because that's a home game, away games, you've got scrap for everything you can."
