Fernando Alonso has ignited a potential war of words with Brit Jolyon Palmer after a recording of an exchange the Spaniard had with Honda McLaren team emerged during the Italian Grand Prix at Monza.
Informed by his team that Palmer had retired during the latest leg of the F1 world championships, the two-time Spnaish world champion exclaimed "Karma" on his team radio.
At the previous leg of the world championships in Spa, Belgium, Palmer had called for Alonso to be penalised after the two clashed midway through the race.
In his second season in Formula One, Palmer complained to his team "come on, Alonso just forced me straight off the track," after Alonso had taken the inside lane when the two drew up side by side.
Driving for Renault, Palmer contended Alonso's driving was "identical" to Kevin Magnussen's controversial move on teammate Nico Hulkenberg.
"We got stuck behind Alonso, who forced me off the track pretty clearly," Palmer told Autosport.
"If you ask me there's nothing between that and what Kevin did to Hulk. It was identical.
"I don't know if he'll get a penalty. We'll see. But that cost me two places.
"If halfway found the corner he just decides to force me off the track, it's exactly the same (as Magnussen/Hulkenberg). It's up to the stewards to decide.

"But, if Magnussen gets a penalty for sure Alonso has to get a penalty as well."
In the event, Alonso, often regarded as one of the greatest drivers in Formula One history, was also forced to retire at Monza in a race which saw a victorious Lewis Hamilton, for Mercedes, take the lead from Ferrari's Sebastian Vettel in the Drivers' Championship.
Vettel was third and now trails Hamilton by three points, but is heavily backed to dominate in the next leg in Singapore.
