Lewis Hamilton is the only worthy winner of this year's world title

Lewis Hamilton Abu Dhabi

Nico Rosberg still has every chance of snatching the F1 title from team-mate Lewis Hamilton, but the Brit is far and away the more deserving champion.

The Mercedes one-two in yesterday's U.S Grand Prix confirmed that one of the German marque's drivers will win this year's world title.

For the 10th time this season, victory went to Lewis Hamilton, who now leads team-mate Nico Rosberg by 24 points with two rounds left to run. The Brit is in imperious form, with his triumph at Circuit of the Americas making it five on the bounce for the world championship leader.

Having been passed for the lead of the race on lap 24, Rosberg followed him home in second for the eighth time this season. And that oh-so-common result makes something very clear: Lewis Hamilton is now the only deserving recipient of this year's world title.

This is not to suggest that Rosberg is performing badly: he has continued to show impressive pace despite Hamilton's run of victories, and appears tough enough to maintain his cool in the face of ever-mounting odds. He has already bounced back once, ending Hamilton's four-race winning streak with victory in Monaco earlier in the season, and could yet return to the top step before the campaign is done.

But that would still not been enough to make the German a deserving title winner. With 10 victories to his name, Hamilton has thoroughly earned the right to be world champion.

There was a period during the summer when you could have argued that the opposite was true. Following the German Grand Prix, Nico led the standings by 14 points. He had barely put a foot wrong all season, while Lewis had hampered his own chances with a number of qualifying blunders and a seemingly frail mentality .

But Nico became unnecessarily frustrated by events at the Hungaroring, where Lewis refused to allow his team-mate past despite a questionable order from the pit wall. They then had their infamous collision at Spa, which could be seen as a direct result of Hungary, followed by an embarrassing public telling-off for Nico.

At this point momentum swung and Lewis has gone undefeated since Belgium. Put more starkly, Hamilton has not finished a race behind his team-mate since July 20 and was last beaten on-track by anyone seven days later.

Rosberg has taken nine pole positions this season but converted only two of those into victory. What's more, he has started three of the past six races from P1 but failed to win any: he lost Belgium because of his collision with Hamilton and was beaten by his team-mate on-track in Japan and the U.S.

Which brings us to another significant point. At no stage this year has Nico come from behind to beat Hamilton to victory. He won Australia from second on the grid after Lewis' car had succumbed to technical gremlins, then triumphed from pole in Monaco after a contentious qualifying session. He won from second in Austria, but on this occasion Felipe Massa had taken the only non-Mercedes pole of 2014. Nico then clinched victory on home turf in Germany from pole.

On the other hand, Lewis has beaten his team-mate on-track a number of times. He did so in Bahrain and Hungary, at Suzuka and COTA, and could well have done so at Spa were it not for Nico's clumsy overtaking attempt.

Heading to Interlagos, Hamilton holds a 24-point championship advantage over Rosberg. Under normal circumstances he would only need to beat his team-mate in Brazil to ensure his second world title, but the universally-loathed double points rule will ensure that their battle goes down to the season finale in Abu Dhabi.

Given the Mercedes' pace advantage, the only way Rosberg can win the title now is through a DNF for Hamilton. The Silver Arrows are so far ahead that even if Lewis is roundly beaten by Nico, he should still have the pace to finish in P2. As such, the Brit can afford to finish second to Nico in both races, even with double points, and still clinch the championship.

Mercedes are desperate to ensure that this world title battle is not decided by a technical problem. Since clinching the constructors' crown, bulletproof reliability has been their chief focus. That makes a Hamilton title victory seem very likely.

And if he does wrap up the championship, it will be a case of the right driver taking home the spoils. Nico Rosberg has been good this season, but even he must admit that Lewis Hamilton has been better.
