The intense rivalry between Lewis Hamilton and Nico Rosberg has increased heading into the final race of the season with Rosberg taunting his Mercedes teammate by urging him to “drive cleanly.”

Tensions between the pair have spilled over on two notable occasions this season, at the Monaco Grand Prix in May and the Belgian Grand Prix in August.

Only 17 points separate Hamilton, the championship leader, from Rosberg ahead of Sunday’s Abu Dhabi GP.

With double points up for grabs, Rosberg can clinch his maiden title – and deny Hamilton his second – if he wins the race and Hamilton finishes third.

Hamilton has won five of the past six races, and finished second behind Rosberg in the previous race in Brazil.

“I need a bit of help from Lewis so that he doesn’t finish second. Hopefully Lewis can come up with something,” a grinning Rosberg said at a news conference, glancing across at Hamilton, who remained unmoved.

“It’s going to be intense, a great battle.”

At the Monaco GP, Hamilton was infuriated when Rosberg crashed under no pressure at the end of qualifying, forcing the session to be stopped and denying Hamilton an almost certain pole position as he was set to beat Rosberg’s leading time.

Then, in Spa, Hamilton was livid after Rosberg nudged into his side, puncturing his tyre and ending his race.

He even accused Rosberg of doing it on purpose and the feud escalated to such an extent that team management had to publicly chastise their drivers in order to keep the situation under control.

Hamilton was asked if there was something he could do to ensure a clean race on Sunday, to which he said there was not, before adding “I don’t really know what else to say, we have to go into the race believing that’s going to be the case.”

That irked Rosberg, who snapped at the British driver.

“Yes, Lewis can do something to keep it clean, which is drive cleanly himself,” Rosberg said.

In Brazil, Hamilton missed out on a sixth consecutive win and 11th of the season after making a mistake and spinning. Although he recovered to take second place, Rosberg has taken encouragement from it.

“I need to do what I can to try and put the pressure on (Hamilton). In Brazil, Lewis made a mistake. There is a chance. So I need to keep going like that,” Rosberg said.

“A lot of things can happen. It can happen as easily as a Williams having a great start and slotting in between us two.

“This track is one of the most difficult to overtake.”
