The last time Sheffield United played in the Premier League current Cardiff City manager Neil Warnock was their boss.
That was 12 years ago and the Blades have since been relegated twice and languished in League One for six years.
Now Chris Wilder is in charge and he has lead them back to the top flight. Cardiff, meanwhile, will be coming the other way back to the Championship after one season.
Ahead of their return to the big time, should Wilder consider any of the players who have performed under Warnock in 2018/19?
Experienced head – Bruno Ecuele Manga
Of the three teams that were relegated, the Bluebirds had by far the most superior defensive record. They also conceded fewer goals than Bournemouth.
Manga was at the heart of that, starting 37 of their league matches last term and coming on as a substitute in the other.
The 30-year-old’s ability to also play at full-back means he could fit Wilder’s unique 3-5-2 style. Manga could well be utilised as one of the overlapping centre halves.
What makes the Gabon international even more appealing as well is the fact he is out of contract this summer.
Mr versatile – Callum Paterson
There is unlikely to be a huge amount of interest in Paterson and Warnock will probably expect to have him in his squad next season.
However, what might make the Scotland international an attractive prospect to Wilder is his versatility. Paterson has played as a striker, central midfielder and wide man in 2018/19.
The long shot – Josh Murphy
Murphy was signed by Cardiff from Norwich City upon their promotion in 2018 for a fee of around £11m (BBC).
In what has ultimately proven to be a disappointing campaign for the Welsh club, the winger has been a standout performer.
Which is why it is unsurprising Football Insider reports Burnley and Crystal Palace are interested in signing Murphy.
Also, with the 24-year-old generally operating from the flanks he doesn’t obviously fit into Wilder’s system. However, he can play anywhere in the front line and has bags of potential.
