BOSS Paul Warne says Rotherham United's magnificent FA Cup show will count for nothing unless his side repeat the same sort of form in the league.
The Millers stunned Premier League Everton in the third-round tie at Goodison Park this afternoon by fighting back from a goal down and taking the clash into extra time.
They eventually lost 2-1 and now head back to their Championship survival fight, starting at Derby County next Saturday.
"There are positives only if we back this up," said Warne who watched Matt Olosunde score his first goal for the club to cancel out Cenk Tosun's ninth-minute opener.
"I don't want the lads to get on the bus and think they have got life sussed and that we will be okay.
"The league will be a different game to today. This was a life experience for them. It is an honour to play at this great stadium.
"But it is back to business next week and we need to build on this with some really good performances in the next 20 games to try to retain our status."
Rotherham had the game's best chance in the first 90 minutes and looked capable of springing a huge knockout shock before Abdoulaye Doucoure scored the winner three minutes into overtime.
"I really believe in this group," Warne said. "I always have. They give me everything they have got and if nothing else we can now give the league a good run."
Carlo Ancelotti's Everton team included England centre-half Michael Keane and Colombian midfielder James Rodriguez, who once cost Real Madrid £71m, but they were second best to the Millers for long spells.
Toffees assistant manager Duncan Ferguson: "It was a tough game for us and one we were delighted to get through.
"You're always fearing the worst when they get a last-minute corner so there was a wee bit of relief at the end."
