When Rotherham manager Paul Warne was first asked about the prospect of taking his side to Manchester City in the FA Cup he grimaced.
For the Championship Millers, full of players who played in League One last season, going up against the current champions of England was not a particularly appealing prospect.
No one really ever thought a shock was on the cards, especially when they saw the team Pep Guardiola put out.
Full of world class players that cost £390million to assemble, and global stars to bring off the bench, what realistic chance did Paul Warne's side have?
Not much of one was the answer and the Millers went down to a 7-0 defeat, even though they can say they gave it their all.
Goals from Raheem Sterling, Phil Foden, Gabriel Jesus, Riyad Mahrez, Nicolas Otamdendi, Leroy Sane and a Semi Ajayi own goal did the damage for City on an afternoon where they could have hit double figures.
The Millers will be disappointed they shipped seven goals but will know a much more important game comes in the Championship at Ipswich next week.
“I am pleased the final whistle went, we came across a very good Man City team that wanted to win,” a realistic Warne said. “I don't think until you witness it with your own eyes you realise how good they are.
“Those two quick goals before half-time killed the game and at half-time it was more damage limitation.
“The gulf in class was there for everyone to see. I was pleased with some performances and I would like to think our lads will learn something from the game.”
Against perhaps a stronger than anticipated team it was always going to be a matter of how long the Millers could hold out.
Jesus had already hit the woodwork by the time the visitors' defence was breached in the 12th minute.
The Millers did not track Sterling's run and the England international cut inside and slotted home.
Warne's men battled hard, but two goals in two minutes before half-time broke their resistance.
Foden was fortunate with his goal as his first touch bobbled off his knee and past Rodak before Ajayi put through his net trying to clear Kyle Walker's dangerous cross.
Sterling set Jesus up to tap in early in the second half with a burst of pace and then Mahrez's low shot made it five.
Otamendi headed home from a corner to make it six and Sane's deflected effort confirmed Rotherham's heaviest defeat since 1995.
