Darren Ferguson has gone into information overdrive with his players in an attempt to quickly ingrain his own style and structures.
The Scot takes charge of his third game in charge of Doncaster at Millwall tonight after contrasting results at Shrewsbury and Peterborough.
With Rovers sat 22nd in League One, time has been of the essence on the training pitch.
“The biggest thing for me is trying to implement how I want to play and also get results,” said Ferguson.
“That’s the most difficult thing at the moment.
“We are going to be a bit more expansive. Our full backs are going to be higher. That’s how I want to play. So you run the risk if you lose the ball you’re going to get done on the counter.
“We were a little bit too open [on Saturday] and that’s why we changed it - and we were unlucky to lose the third goal so quickly after half time. That one kills the game.
“There’s so much work to do and we’re trying to get as much information into them as possible, probably more information than they’ve had in a long time.
“But it’s got to be done quickly because we’ve got so many games and I want to get through this week with some positive results, and then we’ve got a free week just to settle things down a bit.
“We’re trying to get a lot into them quickly, without confusing them.”
He continued: “We’ve worked on two different formations and we went to another different one on Saturday. I said when I came in the door I wanted to be flexible, especially within a game to be able to change things. That’s something I do believe in.
“The most important thing is when you’re giving information, are the players digesting it? Do they understand it? We’re giving clear messages to them.
“And then they’ve got to have a belief among themselves to go and impose themselves with that system. They’ve got to have confidence in doing that.
“They’re the biggest things, and as a manager I’m trusting them to be able to do it.
“I did think about a different system on Saturday playing against Peterborough but I trusted them. That’s not me having a go at the players. They know we’ve got to be better both on and off the ball.”
In-form Millwall have lost just one in six and won at Sheffield United at the weekend.
“They’re going well. They’re a big, physical team,” said Ferguson.
“We’ve got to make sure we impose ourselves on them and, if we can, control possession and quieten their fans.
“The players know what to expect. We’re going to have to battle to earn the right to play against these.
“That’s one thing you’ve got to do away from home, better than we did on Saturday anyway.”
Gary MacKenzie is definitely out. Ferguson will make late calls on Nathan Tyson, Keshi Anderson and Rob Jones.
