Tony Mowbray says he's prepared to tinker with his Rovers side going forward if it improves the balance of the team and yields results.
In the manager's two full seasons in charge, Rovers have mainly played with a 4-2-3-1 formation, usually with Danny Graham spearheading the attack.
But moving forward, Mowbray says he's prepared to change things up to benefit the side, which has been tried and tested with the usual system.
The two sides who earned automatic promotion played with slightly unusual systems, with Sheffield United opting with three at the back, whilst Norwich's free flowing style saw the Canaries operate with two attacking, homegrown wing backs.
And the boss admits he's prepared to change going forward.
"As we develop this football club, we'll look to play different systems against different opponents," he admitted to iFollow Rovers.
“After spending two years drilling the drills into the team, it’s difficult to change things mid-season.
“We’ve played with a three at the back at times, sometimes it’s worked and sometimes it hasn’t.
“In this league, the better teams can take advantage and pick holes when you do go with three at the back.
“Depending on who we sign, going forward we’ll look to pick a system that has the right balance for us.
“It’s about doing the work on the training ground. If we spend pre-season working on things and feel confident then you can play a formation that suits you the best," he added.
“We'll just try and find the best way to compete in each game and I feel that for a long time last season we’ve been competitive."
