SOURCES in Germany say that Max Verstappen's management team are having talks with Mercedes following this weekend's Miami Grand Prix.
Verstappen's dad, Jos, and his manager, Raymond Vermeulen, are expected to meet the three owners of the F1 team; Toto Wolff, Mercedes-Benz CEO Ola Kallenius, and Ineos and Manchester United shareholder, Sir Jim Ratcliffe.
Wolff has made no secret of the fact he would love to sign Verstappen as Lewis Hamilton's replacement.
Verstappen, 26, is under contract at Red Bull until 2028.
But boss Christian Horner has said he will not stand in his way if he wants to quit.
Verstappen Sr has admitted they are considering the three-time champion's options before the 2026 regulation change.
Speaking during the Rally de Wallonie, via RacingNews365, he said: "I think everyone wants him, only I think Max is right for the moment.
"He has a fast car, but we also have to look further to 2026, so we are letting everything come to us at the moment. We stay very calm and see what will happen."
On talk of signing Verstappen, Wolff said in Shanghai, China: "There are so many factors that play a role for a driver joining.
"Clearly when you look at it from the most rational point of view, you can say: ‘That’s the quickest car in the hands of the quickest driver’. But I don’t think this is the only reason you stay where you are.
“I think, for simple minds, that might be the only reason why you stay in a car and that’s it but maybe there are more depths for some people that consider other factors too. I think that Max has that.
"In that respect, are we able to convince him? I don’t think it’s a matter of convincing.
"I think that Max knows motor racing better than anyone, he will take decisions that he feels are good for him.
"I think a few factors play a role, but he’s the one that is going to trigger some more domino stones to fall in afterward. Everybody is waiting for what he’s going to do."
The Horner-storm which has surrounded the team has been cited as a key factor in reports suggesting car designer Adrian Newey could leave the team amid heavy links to Ferrari and Aston Martin.
The internal power struggle at the team also saw advisor Helmut Marko placed under investigation, which is said to have left Verstappen angered and ready to leave if Marko was axed.
Verstappen said at the time: "I am loyal to Helmut.
"He is a big and important part in my decision making and important he stays within the team including everyone else.
"It is important we keep people together because if an important pillar falls away, that is not good for my career as well.
"So for me, Helmut has to stay. He has built this team with [Red Bull co-founder] Dietrich Mateschitz from day one and been loyal.
"You need to give the man respect for what he has done and that comes back to loyalty and integrity and is important to why he stays part of the team."
British racing icon Johnny Herbert then suggested a Verstappen-Mercedes deal was edging closer last month.
He told The Sun: "They're very close to pushing [Max Verstappen] out of the team, I've heard they are getting quite close with the deal with Mercedes."
Nico Hulkenberg is the latest F1 star to confirm their position on the grid next season after picking up a seat with Sauber, opening the door for Haas to sign Brit teen Oliver Bearman.
