Mauricio Pochettino wants Manchester United to prove to him that he's their No.1 choice before taking the top job at Old Trafford.
The Argentine was in consideration for the role before United appointed Ole Gunnar Solskjaer and was thought to be one of those looked at before the club opted to hand Ralf Rangnick temporary charge after Solskjaer's sacking.
PSG sporting director Leonardo cast doubt over Pochettino's long-term future in Paris after a Champions League elimination at the hands of Real Madrid, suggesting now was not the time to discuss matters beyond the current season.
This has prompted increased noise around the 50-year-old potentially moving back to the Premier League, but it's clear he needs reassurances.
Should Man Utd move for Pochettino? Have your say in the comments section

According to The Mail, Pochettino needs to feel he's top of United's list after being overlooked before.
He is not the only man to have been linked, with Ajax's Erik ten Hag and Spain manager Luis Enrique among the others thought to be in the mix.
If United do pursue Pochettino, however, it could end up paving the way for the club to also add former Spurs striker Harry Kane to their ranks.
Renewed links between Pochettino and United come with a warning, though, with former Man Utd striker Dimitar Berbatov telling Mirror Football his old club need to continue exploring their options.
"Although this is a black spot on the reputation of Pochettino, I don't think this is going to lessen his reputation in England. He's still the frontrunner to be the manager of United," the Bulgarian said.
"But I would like to see other people interviewed for the position, just open up your eyesight and interview other people to see what they are going to say, what they're going to bring to the team and then make the final decision.
"I sincerely hope that when they make the decision, this time it's going to be the right guy."

Despite PSG's European exit, they are still on course to comfortably win the Ligue 1 title for the first time under Pochettino.
The manager could only finish second behind Lille last term, after replacing Thomas Tuchel midway through the season, but the Parisian club remains 13 points clear despite a weekend defeat to challengers Nice.
In several years in the Premier League with Southampton and Tottenham Hotspur, he never finished higher than second, but did lead Spurs to four successive top-four finishes during his time at White Hart Lane.
Man Utd's own top-four status hangs in the balance, with fourth-place Arsenal sitting a point clear of Rangnick's side while holding three games in hand.
