Just a few weeks ago, it seemed like a mammoth task for Lewis Hamilton to catch Nico Rosberg at the top of the Driver's Championship rankings.
However, two consecutive wins for the Brit in the United States and Mexico has brought a slight glimmer of hope.
Heading into the penultimate race of the season at the Brazil Grand Prix, Hamilton trails his Mercedes teammate by 19 points, which was a massive 33 after the conclusion of the Japanese Grand Prix.

Hamilton has already made the perfect start in Sao Paolo after finishing fastest during the first practise, but still faces an uphill task against his German rival, as Rosberg just needs to finish second in both the remaining races to clinch the title.
But, former World Champion Jenson Button believes that a possibility of rain could tilt the race in Hamilton's favor, which could force the race for the crown to head into the final contest of the season in Abu Dhabi.
Button said: "If the race is dry, Lewis is the only guy who's going to challenge him. He's just got to get through Turn One.
"Nico's got a big enough lead to finish second in both races but I think the idea of a wet race will worry him. Then the pressure is there, definitely. One small mistake and it could end in disaster.
"It it's dry it's a walk in the park but if it's wet here, then I'd pick Lewis for the title. If it's dry here, then I'd say Nico."
Rosberg has won in Brazil for the last two years, but the championship leader has suffered setbacks this season during heavy rain.
Hamilton, on the other hand, thrives in wet races. The 31-year-old perfectly navigated the race in Monaco, where Rosberg found it extremely difficult, during a downpour and also sealed first place at a soggy Silverstone.
Despite Button's analysis, Rosberg remains confident and unhinged prior to the race. The German has insisted that he does not feel the pressure due to the possibility of rain.
He commented on the prospects of a wet race: "I wouldn't mind both, as it makes no difference. I've felt comfortable on this track even in the wet."
Rosberg has portrayed a calm demeanor throughout the campaign, whereby suggesting that he is unhinged by Hamilton's relentless efforts to topple him from top spot.
Rain would definitely make it interesting on Sunday and a slip up from Rosberg could put his title challenge at risk.
