One thing that is certain to put the fear into the eyes of defenders is blistering pace, and Michael Ihiekwe has had to face that from the Millers' latest recruits during the last week of training.
Rotherham United supporters have already seen a glimpse of what Chiedozie Ogbene can do following his arrival from Brentford, with the 22-year-old making an earlier debut than anticipated when he was thrown into the action after 12 minutes against Tranmere Rovers.
Paul Warne then added to his squad further by signing another exciting forward player on Deadline Day, this time in the form of Jake Hastie. Despite only seeing him at Roundwood on a couple of occasions, Ihiekwe has been impressed with what he has to offer.
He said: "Having both Chieo and Jake coming in gives the manager more options and it keeps opposition teams guessing. If you're a full-back playing against us, you're probably expecting to face our front three and it be a different type of test.
"We saw when Chieo came on against Tranmere that he's capable of causing all kinds of problems and that gives us another dimension. He's rapid and he's so sharp in training too, he's a nightmare to deal with at times!
"Jake is frighteningly quick as well. He's only trained with us a couple of times so far, but you can see that in training and he certainly has a few tricks in his locker. We've now got two direct wingers, so I'm sure they'll make an impact for us."
Both Ogbene and Hastie could feature on Saturday afternoon when the Millers make the short trip across South Yorkshire to face Doncaster Rovers, and they'll be joined by at least a 3,000-strong contingent of travelling supporters.
In what is a highly anticipated fixture in Sky Bet League One, Ihiekwe is hoping that he and his teammates can build on their excellent away form by picking up another set of three points to add to their tally.
He said: "It's a derby, so although it's early on in the season, it doesn't matter what you've done in previous games. These types of fixture are all about whoever performs on the day, and it will be a tough test between two teams striving for success.
"Despite that, it's one I'm confident we can do well in. We've looked solid away from home and our two clean sheets have come on the road too, so we want to maintain that start in front of the travelling fans."
