Even in the midst of Fernando Alonso's anger and warnings, rumours about his future just will not go away.

Speaking with foreign-language reporters on the eve of the Singapore grand prix weekend, the Spaniard flew into a rage when faced with the latest wild speculation about his impending Ferrari exit.

Hinting that the leaks are coming from within Maranello, Alonso had said on Thursday: "If I do say something, I will do it in a few weeks time and somebody will not like what it is."

Still, the rumours keep coming.

The latest are being heard from the Japanese corners of the paddock, just two weeks ahead of the country's own grand prix at Suzuka.

Suzuka, of course, is owned by the Japanese manufacturer Honda, who have been repeatedly linked with a big-money effort to sign Alonso to McLaren for 2015 as the highly-anticipated works F1 collaboration kicks off.

Speed Week reports that Japanese sources are saying Honda is prepared to 'move mountains' behind the scenes at Suzuka early next month to convince Alonso to leave Ferrari.

The report said Honda is apparently fully prepared to buy out the remainder of his lucrative Ferrari contract to make it happen.

Crisis-struck Ferrari, however, having already parted with big names like Domenicali, Marmorini and di Montezemolo in 2014, will not want to now lose Alonso.

"Without Fernando Alonso," Mercedes team chairman Niki Lauda is quoted as saying, "Ferrari would be nowhere."
