With Lewis Hamilton moving to Ferrari, Mercedes boss Toto Wolff hinted at a surprise return for a retired F1 legend.
The seven-time world champion's shocking Mercedes exit has left a gaping hole in the Brackley outfit's garage.
While Red Bull star Max Verstappen remains at the top of the list for the coveted seat, other names like Carlos Sainz, Fernando Alonso, F2 driver Kimi Antonelli, and even the recently retired Sebastian Vettel have been thrown around.
Speaking in the press conference at Suzuka, Wolff acknowledged Vettel's enduring talent, saying, "Sebastian is someone you can never discount.
"His track record is phenomenal, and sometimes maybe taking a break is also good to evaluate what's important for you and re-find your motivation."
The Austrian boss further emphasised that a decision is still far off. "We haven't taken the decision yet and it's not something we plan to do in the next few weeks," he added.
"The driver market is very dynamic and some of the really good guys are about to sign for the other teams and we want to continue to have these discussions."
While Wolff remained cautious about committing to a specific driver profile, his comments about 're-finding motivation' could be a subtle clue pointing towards a sensational return for the German champion.
