Rohl gave an insight into his tactical approach, with Rangers having struggled defensively this term and also been blunt in attack.
“My focus is on my person, what I can bring to this football club,” the former Sheffield Wednesday boss said. “I see so much potential.
“My football, what I want to see on the pitch is intensity, it’s sprinting, it’s a togetherness and a playing forward style because we want to create chances, we want to create goals.
“We have to speed up our game. We want to attack the last line. If you do it again, we create more chances and we have more goals.
“We have to defend as a group, as a unit much, much better with a lot of aggression in the duels.
“We have to press well, we have to hunt, we have to go in the counter pressing and we have to play with intensity and it starts from the striker to the defender. If you do it as a unit, then it’s very hard to beat us and to break us down.
“At first you have to win games, then you can speak about playing attractive football. We need wins in a row. With wins in a row, you can create self confidence and absolute belief.”
Last week, Rohl seemed to be out of the race to join Rangers, shortly after former Ibrox manager and ex-England captain Steven Gerrard had also withdrawn from the recruitment process.
Kevin Muscat appeared to be the favourite but any deal for the Australian fell through on Sunday, at which point Rohl came back to the fore.
Rohl described meetings with the Rangers hierarchy as “outstanding” and said he “never stopped the communication”.
“It was immediately a great relationship between all of us in the meetings,” he said. “I felt the trust.
“You can be the first, the second or third choice. It’s important that you win the next games. I cannot tell you which choice, I can just tell you that I’m here and it gives me belief that I was the first choice.”
