The acrimonious relationship between the two during their year together at McLaren in 2007 is well documented. The duo not only fought on the track but also off it.Following qualifying for the Hungarian GP, Alonso was stripped of his pole position for blocking Hamilton in the pits during qualifying, preventing the then-rookie from challenging for pole position.
Added that, there was the Stepneygate spy scandal where McLaren received secret technical information about Ferrari's 2007 challenger.
The scandal reportedly came to light when Alonso threatened to report team boss Ron Dennis to the FIA if he was not handed number one driver status.
But it now appears that those were not the only controversies during the Spaniard's time at McLaren.
According to The Star, Tom Bowers' recently published biography "No Angel: The Secret Life of Bernie Ecclestone", claims that Alonso asked Dennis to sabotage Hamilton.
The book alleges that, hours before the start of that tension-fraught 2007 Hungarian GP, Alonso approached Dennis, telling him to short-fuel Hamilton's McLaren so that the Brit would run out of fuel and fail to finish the grand prix.
And although Hamilton and Alonso have insisted in recent months that they have buried the hatchet, these claims may spark yet another war between the two World Champions.
