Paul Dickov has asked for patience ahead of the big kick off.
The Scot has been keen to manage expectations following a disruptive summer.
Dickov’s men hope to hit the ground running in their League One opener at Yeovil Town on Saturday.
But he has warned supporters not to expect too much too soon from his newly streamlined squad.
“We want to be competitive this season,” said Dickov, when the Free Press asked him about his target for the season.
“We know it’s going to be difficult and we know it’s not going to happen overnight.
“The group we’ve got here now has only been together for a week really, which is not ideal.
“You’d have liked a full six weeks with the players that you’ve got and the ones that you’ve signed, but there’s no point dwelling on it. You have to move forward.
“With the disruption that’s happened, there’s a really good spirit in the squad and that’s a big positive for me,” he added.
“If you’ve got that, you’ve got half a chance.
“But we need a bit of patience.
“We might go to Yeovil and it might click straight away. It might take a few weeks for that to happen.
“But what we will do is go down there in a positive frame of mind and, as always, go with the intention of winning the game.”
Dickov was handed a major boost after skipper Rob Jones successfully returned from nine months out in Rovers’ final pre-season friendly against Rotherham on Saturday.
Jones has declared himself fit for this weekend.
“Rob’s important to us,” said Dickov.
“We need leaders and we need experience in the team - and that’s what Rob brings.
“He brings a lot out on the pitch and also in the changing room.
“I thought in the first half against Rotherham we looked strong defensively against a very good team.”
Dickov was hopeful of concluding a deal for a back-up goalkeeper this week.
