McLaren are determined to hang onto Lewis Hamilton and the team have reportedly increased their contract offer to the 2008 World Champion.
Hamilton, whose deal with the Woking squad runs out at the end of the season, he has been strongly linked with a move to Mercedes with many claiming the German manufacturer are offering him a lot more cash than his current team.
The 27-year-old refused to discuss his future during the Singapore Grand Prix, but he is expected to make an announcement in the coming days.
McLaren's executives were in Singapore over the weekend and media reports suggest they have upped their offer.
Hamilton's current five-year deal is worth about £75million, or £15m a year, but McLaren's initial offer was thought to be well below that while Mercedes were willing to fork out more.
The Guardian though reports that 'McLaren have increased their offer to Lewis Hamilton in an attempt to see off a bid from Mercedes, placing an extra £2m a year on top of the £10m already on the table'.
It adds: 'According to sources at McLaren, the money on offer from Mercedes is not as substantial as the £20m a year that has been reported. It is fair to say that Mercedes, who hold a board meeting on Wednesday, have been prepared to match McLaren's terms, with more money on offer through image rights.'
Meanwhile, Formula One commercial rights holder Bernie Ecclestone believes Hamilton is not sure what to do.
"I don't think Hamilton knows what he will do," the F1 supremo is quoted as saying on ESPNF1.
"These last couple or three races he has been doing very well. Before that, why he was upset I don't know, but he was definitely going to move no matter what. He had made up his mind that he was going. Whether he has changed now a little bit I don't know."
