Millers boss Paul Warne reflected on his side's 2-1 victory at Preston North End
"I thought that Preston were easily the better side first half and asked us loads of questions," said Warne.
"I think we were lucky to go in at half time with a clean sheet and I don't think our performance justified a 1-0 lead at that point.
"We changed it a little bit and we got our wing backs to play a little bit deeper. We got our foot on the ball a bit better second half and I thought that we were really good.
"We took another goal and I thought our play deserved a third - which was the only disappointing thing.
"On another day it might have been a foul on Viktor - I didn't think it was from where I was.
"We just had to defend a bit of a siege because whenever there is only a goal in it, teams throw everything at it.
"Alex [Neil] put some good subs on and I'm just well happy to hear the final whistle.
"We had to make changes and I knew that we would be criticised no matter what the result was. Last time we played a Wednesday and a Saturday, we did really well at Boro and then just struggled a bit with energy against Swansea. I had to make changes this week, it wasn't easy, but I took five key players out.
"We had a spring in our step and the lads that came in did really well.
"Without a shadow of a doubt, my outstanding performer was Wingy. He played a couple of defence-splitting passes.
"Overall, we're pleased with that win but we now have to recover for Tuesday and go against a different competitor.
"I thought their work rate was good and I thought they should have scored again second half. We ask a lot of our strikers, they aren't like a Number 9 that stands there and does the odd overhead kick, anything but. They have to work so hard out of possession."
Warne was pleased his reshuffled side continued with the hard work instilled in them to secure a third straight away in.
"Their work ethic today was great," continued Warne."
"It was always the intention that whoever I started up top I would take off after 60 minutes and we'd flip it because the demands are so great."
On the unfortunate early withdrawal of Jamie Lindsay, Warne said:
"I've got no idea how bad it is. He's getting a scan on Monday and I once pulled my hamstring on the Saturday and played on the Tuesday so I'm hoping he's one of those superhuman people.
"He is in pain now which isn't a great sign. I'm only guessing but if he has pulled it it could be two, three or four weeks."
