Paul Dickov insists he has seen plenty of positive signs as he looks to bring players into the club and tie down those out-of-contract.
Rovers are unable to offer any new contracts until after July 18 when the John Ryan-Louis Tomlinson takeover of the club is set to be complete.
But Dickov is confident he will secure his targets soon after he gets the green light.
Long-rumoured transfer targets Peter Clarke and James Bailey both played 45 minutes at Bradford Park Avenue on Wednesday night, as did trialists Jon Otsemobor and Elliott Kebbie.
Kebbie is a former Leeds United youngster who joined Atletico Madrid at the age of 17. He spent the second half of last season at Hull City.
“There are a few players in at the minute that we’re having discussions with – positive discussions,” Dickov said.
“And once the takeover is confirmed on the 18th hopefully we can start announcing a few things.
“They’ve been in training with us.
“James is a player I’ve always liked since his days at Crewe and Peter is experienced, he knows how to get promoted out of this division.
“Elliott has got a decent history behind him.
“He went from Leeds to Atletico Madrid and he was at Hull last year. He’s another one over the course of pre-season we’ll be keeping tabs on.
“We’re in discussions. There’s nothing we can do until after the 18th.
”We’re very hopeful we can announce a few signings after that.
“We’ve said all summer that we’re chatting to people.
“The players we want to get in are players we want to get out of the division with. Experienced players, players with energy, players who can pass the ball.
“It’s not just the lads who are here tonight, there’s other things going on behind the scenes as well.”
Out-of-contract players James Coppinger, Paul Keegan, Jon Maxted, Harry Middleton and Alex Peterson all played in the Bradford Park Avenue friendly.
And Dickov remains confident they will all sign after July 18th, despite being unable to offer pre-contract agreements.
He said: “We want them all to stay and we’re positive they will.
“It’s difficult because we have to wait until we can get it done but what I will say is there are a lot of positive signs.
“We can’t have pre-contract agreements, we’re talking to players at the minute.
“On a positive view of it, would they be here if they weren’t thinking of staying?”
Dickov revealed the club remains in discussion with Ross Turnbull, whose contract has expired, and hopes to have the goalkeeper on next week’s trip to Portugal.
He said: “Ross is another player we’re in discussions with at the minute.
“We’re hopeful Ross might come out to Portugal with us and then it’s watch this space after the 18th.”
