The argument between Lewis Hamilton and Felipe Massa in Singapore has taken a new twist after it emerged that the Brazilian was encouraged to 'destroy' his rival's race in a radio call from the pits.

Massa and Hamilton clashed on track in both qualifying and on race day in Singapore, with the latter incident forcing Massa to pit for a puncture and leading to Hamilton picking up a drive-through penalty.

Following the race, Massa then confronted Hamilton as the McLaren driver prepared to carry out a post-race interview with Dutch TV, with the Ferrari man pulling no punches with his view on Hamilton's driving in the aftermath of the event.

However, further fuel to the argument between the pair has now arisen following the release of the race edit of the Singapore GP on the official F1 website, which includes a radio call from race engineer Rob Smedley to Massa during the race.

In the message, Smedley comes on the radio to tell Massa to 'hold Hamilton as much as we can' and to 'destroy his race as much as we can'.

Although the race edit shows the call being made prior to the controversial collision on race day, it isn't clear when the message was actually sent from the pits, with the radio call having not been included in broadcasts that went out live as the race was taking place.
