Manchester United will face Atletico Madrid in the last 16 of this season's Champions League.
Some United fans will be confident of overcoming the Spanish champions after avoiding Paris Saint-Germain in Monday's controversial re-draw.
But comparisons between Atletico manager Diego Simeone and legendary Red Devils boss Sir Alex Ferguson will concern many supporters.
The Argentine, like Ferguson at Old Trafford, has been in charge of the same club for a long time and delivered success.
During his 10-year reign at Atletico, Simeone has won eight trophies - including two La Liga titles - and reached the Champions League final twice.
Should Manchester United hire Diego Simeone as their next permanent manager? Let us know in the comments below!
He's also managed to consistently compete with Real Madrid and Barcelona in Spain, despite having significantly less financial power.
Simeone was even linked with the manager's role at Old Trafford in 2014 after David Moyes' regrettable nine-month spell in charge came to an end.
And, speaking in May 2018, Atletico striker Antoine Griezmann insisted the job his current boss is doing is similar to the one Ferguson did at United.
"What 'Cholo' [Simeone] is doing for the club is historic," the Frenchman told UEFA.
"It's like what Ferguson did with Man Utd and hopefully he will win trophies and take the team to the top level because he deserves it.
"I hope he will make history with the club because, thanks to him, we are here.
"You learn a lot under [Simeone]. I think he's the best tactical and defensive coach in the world and he shows that year in, year out.
"It's a joy to work with him. He identifies every player's weaknesses and tries to improve them, making you a more complete player.
"He has helped me grow both on a personal and professional level.
"He will always ask for the best of me and make me do my best, and I'll always be there to help him and help win the games."
And if Simeone can inspire Atletico to victory against United in the Champions League, it will hammer home the Manchester club's desire to hire a long-term manager.
The Red Devils have been longing for a someone like Ferguson since his 26-year reign at Old Trafford came to an end in May 2013.
It is ironic then, that arguably the closest manager in world football to that profile will line up in the opposite dugout, while United's fumbling search continues.
United recently hired Ralf Rangnick until the end of the season and intend to appoint a permanent manager for years to come.
"They won’t bring a hitman in," explained club legend Gary Neville in October before previous manager Ole Gunnar Solskjaer was sacked.
"A hitman who comes in and does a job for two years... we’ve seen a coach with a specific style like Louis van Gaal didn’t work here."
Fellow United legend Paul Scholes said a month later: "Man Utd need a long-term manager to build because they have big problems.
"It will take a couple of years again... to get the squad right and the way of playing right to compete."
Simeone won't be that man - that chance has long gone - but he can certainly make his mark at Old Trafford.
