Chris Wilder's Sheffield United have been partying hard this week to celebrate their promotion to the Premier League.
The Blades battled with Leeds United and Norwich City all season long in the race for top flight football - and all the riches that come with it.
Now, with their promotion sealed, bitter rivals Sheffield Wednesday have taken the bizarre step to congratulate them on their official website.

In a statement that has angered loyal Owls fans, Wednesday's Thai businessman owner Dejphon Chansiri said: "Few things in life unite and divide opinion like football.
"But one thing at this stage of every season is undebatable and I would like to offer the warm congratulations of everyone at Sheffield Wednesday to everyone at our neighbours Sheffield United for their achievement of promotion.
"We may be rivals but we are friends of the same city that holds such unique tradition in the football world.
"Recognition in the Premier League can only benefit Sheffield and we wish United well, whilst promising our loyal supporters that we will be giving our absolute best to ensure Wednesday will be tasting the same success this time next year.
"We must also congratulate Norwich City on their promotion and offer our commiserations to Ipswich Town, Bolton Wanderers and Rotherham United. We wish you a speedy return to the Championship."

But, after a dismal end to 2018 that saw them tinker repeatedly with their coaching staff, the Owls left it far too late to seriously mount a play-off charge.
"Football has gone soft", said one Owls fans, angry to see his club celebrate the success of their local rivals - and could you blame him?
