Port Vale manager Micky Adams is hopeful that planned demonstrations before the opening game against Crawley Town will not affect his team.
A supporters' group have arranged for a protest march to take place prior to kick-off at Vale Park on Saturday.
Adams told BBC Radio Stoke: "We should all unite in trying to get this great club into League One.
"I think it's disappointing when we hear that there's demonstrations before the first league game of the season."
The Vale boss continued: "It will be outside a changing room area where there are players excited about going to play for Port Vale.
"Some don't even know about the politics, some don't even realise there were problems here last season.
"I'm just worried that, 10 minutes before kick-off, they're going to hear things that, let's face it, other fans won't have. I'm appealing for unity."
Adams returned for a second spell in charge of Port Vale in May, having left in December to take charge of Sheffield United.
The 49-year-old has also become a director of the League Two club, after an Extraordinary General Meeting in June left Vale with a non-functioning board.
Football League rules would have prevented Adams from adding any new faces to his squad or agreeing new deals with any players who were out of contract.
"I've been vindicated in becoming a board member," added the former Brighton and Leicester manager. "Without me putting my neck on the block, we would only have 12 players at the moment.
"As I've said before, I don't want to get involved in the politics of it all. I want to be judged as a football manager.
"But to get the players signed that we have and to get the contracts ratified by the Football League, I had to take the stance that I did.
"It's a good job that I did because you'd be sat here talking to me now with perhaps no team on Saturday."
BBC Radio Stoke will have live commentary of Port Vale v Crawley Town at 1500 BST on Saturday, 6 August.
