Darren Ferguson is in no rush to deviate from the 3-5-2 system that has produced some much-needed consistency.
But he has revealed that his team go into every game with another formation up their sleeve - and ready to employ on his say.
Following defeats at Peterborough, a result Ferguson pinned the blame on himself for starting with the wrong system, and Millwall, Rovers have lost just once in their last six games and travel to Cambridge United in the FA Cup this weekend in good spirits.
With the squad low on confidence, the switch to three at the back was a brave one which could have easily backfired.
But after a notable upturn in results and performances, Ferguson is unlikely to alter that shape, although he says retaining flexibility is a key part of his pre-match preparations.
“We have got the flexibility to go to a four,” Ferguson told The Star.
“For every game we always show them what we would do if it’s not working.
“So the players will always know the formation we’d go into if it’s not working within the team that is selected.
“I think that’s important for them.
“But I think as the saying goes ‘if it’s not broken, don’t fix it’.
“We’re looking good at the moment with it but we’re not getting carried away.”
Ferguson switched to 3-5-2 at half time during the 4-0 drubbing at Peterborough, with his side already two goals down.
He began his Rovers reign at Shrewsbury by playing a midfield diamond but the injury to Keshi Anderson has since had an impact on his attacking options.
Anderson underwent surgery on his dislocated ankle this week.
