Rotherham secured their Championship status on Tuesday evening with a 2-1 win against Reading. The result consigned both Millwall and Wigan to League One football next season.
Ahead of the game Millwall striker Lee Gregory said he thought Rotherham would lose to Reading and then hopefully "bottle" it in their final game against Leeds this weekend.
Rotherham manager Steve Evans had a message for Gregory on BBC Radio Sheffield regarding the comments.
A Millwall player said we've not got bottle. I've got 12 bottles of pink finest Champagne and we'll be drinking them for about a week.
Look forward to League One, son, and keep your trap shut.
Evans then appeared on Sky Sports today and was asked about his pledge to wear flip-flops, shorts, a sombrero and sunglasses if his team beat Reading.
He told Rob Whotton that he would if Sky Sports received enough tweets demanding it.
If you get enough tweets to the studio from fans around the country, demanding that they can have a laugh seeing me in shorts, t-shirt, sombrero, flip flops, I will be there with them on Saturday at Leeds, I promise you that.
But it has to be a response from you guys that leaves me with no option.
And don’t forget sunglasses, I have got a very special pair of them as well!
Steve Evans tells us he will wear a sombrero and beach wear at Leeds with strong Twitter support... #SombreroForSteve pic.twitter.com/u184D7Tgte
