Grant McCann was left frustrated with Rovers' performance as they ended the opening day with a 1-0 defeat to Harrogate Town.
Jack Muldoon's second half penalty was enough for the visitors to take all three points from the Eco-Power Stadium.
And McCann was disappointed with the showing from his side.
He said: "I thought we were poor in the first half. We just weren't quite getting there to everything. Credit to Harrogate, I thought they were better than us in the first half and that's disappointing for me to say.
"We knew it was going to take time but I didn't expect the team to be that poor in the first half. We were way off it in every aspect of our game. You don't win football games if you don't get the basics right.
"Second half we showed more fight but still nowhere near the levels we can be."
