BOSS Paul Warne says there is work to do after Rotherham United's second-half dip almost cost them victory on League One opening day at AFC Wimbledon.
Having bossed the first half and led 1-0 at the break, the Millers conceded an equaliser after the break and needed a late goal to seal the win.
"We were unplayable at times in the first half," he said. "But I wasn't happy with the second half. We have a lot to work on."
Record buy Freddie Ladapo scored a debut goal to put Rotherham in front and Clark Robertson's low 84th-minute shot was the match-winner following Joe Pigott's 50th-minute leveller.
"I think we should have gone in at the break with a bigger lead," said Warne who praised the backing of the Millers' sold-out away contingent.
“Wimbledon caused us all sorts of problems at the start of the second half.
"It was disappointing conceding from a set-piece. The impetus went towards them. But we still had enough chances to win.
“I’m happy with the victory but there is more to come.
“I’m asking a lot from the lads physically and I’m happy with the bench. I thought the subs had a good positive impact, Wilesy (Ben Wiles) especially.
“They just give us that bit of energy on a hot day on the opening day of the season when everyone was fatiguing."
