Boss Paul Warne's reaction as Rotherham United lose to Luton Town
Rotherham were beaten by a 70th-minute James Collins volley and could have conceded more times after the break at AESSEAL New York Stadium.
"I didn't think we had a response," Warne said. "I don't know whether it was a step too far.
"We didn't change the way we were playing. We just didn't have enough in the final third tonight. We definitely need to freshen the team up."
The Millers were the better side before the break but Luton came on strong and there was little reaction from the home side after they fell behind.
"I thought we were really good first half," Warne said. "We didn't create enough clear-cut chances but I thought we dominated the play. Our set-pieces weren't great.
"Second half, we weren't anything like we have shown in previous games. We hadn't made many changes. Maybe it was a fatigue thing.
"If we had gone 1-0 or 2-0 up in the first half it might have been a different story. We just couldn't handle Luton for a 15-minute period in the second half. They outplayed us. We were hoping to get something, but it wasn't be."
Town boss Nathan Jones, a former teammate of Warne's at Yeovil Town, said: “We were sluggish first half and we got overrun in midfield. That's not something that normally happens.
"We went up a gear in the second half and deservedly got the win."
