Lewis Hamilton is on the verge of leaving McLaren to drive for Mercedes next season, according to BBC F1 chief analyst, Eddie Jordan.
The former team boss says Hamilton will replace Michael Schumacher, who will retire from driving for a second time at the end of the year.
"I believe Hamilton and Mercedes have already agreed personal terms and a deal could be imminent," Jordan said.
F1 boss Bernie Ecclestone hinted last Sunday that Schumacher was retiring.
Ecclestone told Jordan on BBC One: "I'm sorry that he's leaving us not being a winner, because he is a winner."
Asked if knew whether Schumacher was retiring, Ecclestone added: "I don't know, I don't know."
Confronted with Ecclestone's comments, Schumacher insisted after Sunday's Belgian Grand Prix that he had not yet decided on his future.
"As I told [Ecclestone] yesterday I had not made a decision," said the German.
Jordan said he had since been investigating the situation and believed Hamilton, who has yet to agree a new deal to remain with McLaren, was on his way to Mercedes to replace Schumacher.
