Matt Wyatt has warned Sittingbourne players not to get carried away if pre-season goes well.
Bourne reported back for training at the weekend and host Conference Premier Welling in their opening friendly on Tuesday.
Brickies won four and drew one of their six warm-up games last summer but had a disastrous start to the season that led to Wyatt and Nick Davis replacing Jim and Danny Ward as joint-managers.
Wyatt said: “I’m not worried about the result against Welling. I just want our players to be brave on the ball, get some fitness and be competitive.
“I’ve been in football long enough to know that pre-season results mean nothing.
“It happened to us last season where we won nearly all our friendlies under Jim and Danny, then lost six of the first seven league games."
Three Sittingbourne players will be missing during the early weeks of the season.
Left-back Jono Richardson and striker Hicham Akhazzan are on holiday in August, while midfielder Nick Dunsdon is away in September.
