Will he? Won't he? Antonio Rudiger's Chelsea future has been up in the air for much of the season.
Chelsea were unable to come to terms with the German defender before the turn of the year and now Rudiger is able to discuss his future with other clubs.
The likes of Real Madrid, Bayern Munich and PSG have all been linked with his signature but a deal is yet to be forthcoming between the Blues' talismanic star and an interested party.
Chelsea are said to have offered a contract worth around £140,00 per week earlier in the season but Rudiger wants to be among Stamford Bridge's highest paid stars to reflect his place in the team.
The 28-year-old is likely chasing his last big contract, and has become the outfield star Tuchel is least likely to rotate after producing some impressive performance under the former Borussia Dortmund coach.
It's easy to see how the parties reach an impasse given how crucial Rudiger has been. With Chelsea's tendency to switch managers, the unknowns of whether the standard can be maintained in another formation and how long the performances will continue means any negotiations will be fraught.
Nevertheless Rudiger's level has never dropped despite the speculation and he doesn't anticipate that changing, with a lot to achieve before the end of the season.
Rudiger said: "In the case of transfer rumours, it is well known that the media always like to add a little more salt and pepper to make the headline a bit more explosive and bigger.
"Accordingly, you will not hear from me until the day of the final decision. We still have a lot to do at Chelsea this season, and my full focus at the moment is on the City game. My agent is currently taking care of everything else."
Ironically, following his comments, reports that the defender's future could lie at Stamford Bridge after all emerged from Germany. The suggestion being that though talks were at first difficult, now things have improved.
While there will be reservations in handing Rudiger a bumper, long term deal, Tuchel himself has nothing but faith his charge.
The former Roma star has showed no signs of distraction, and talks remain underway
Tuchel said of negotiations: "It's in good hands because I trust the club 100% and have trust in my player, so it's a no problem situation for me.
"He's a guy who needs to trust you, he needs to feel the connection, he needs to feel the trust and he wants to feel it by minutes and actions.
"I don't feel Toni that he needs a lot of words, a lot of pampering and coffee talks and invitations to dinners and whatever. He is the top professional, this is what he proves.
"He's very important and nothing has changed - we're in talks."
Tuchel trusts both the player and the club, and it has become more and more clear they trust in him.
The German coach is yet to have been in England for 12 months but has fostered a strong relationship with Marina Granovskaia and Petr Cech.
The outcome of the controversial Romelu Lukaku interview proved that the squad and hierarchy really do back him.
With the potential to land in another final if Chelsea overcome Spurs on Wednesday night, and progression in the FA Cup and Champions League so far this season, Tuchel might be able to repay that.
The club may begin to dream of a long term future for Tuchel, and with that Rudiger staying past June also becomes more feasible.
