#3. Robert Lewandowski - Bayern Munich
Robert Lewandowski has been one of the world's best footballers over the past two years.
The Polish striker has hit peak form over the last couple of seasons, scoring a ridiculous number of goals across all competitions. Lewandowski spearheads the attacking line at Bayern Munich and has been integral to their success.
Lewandowski netted nine times in six group stage games this year, despite facing stiff competition in the group from the likes of Barcelona and Benfica. Lewandowski was a key member in ensuring the side topped the group with a perfect record.
After his recent snubbing at the Ballon d'Or, there is no doubt Lewandowski is out for vengeance this year.
#2. Mohamed Salah - Liverpool
Mohamed Salah has simply been unstoppable ever since the season began.
The Egyptian seems to have unlocked a higher level this year and even before the midway point, he has already registered 20 goals this season. Salah has been Liverpool's attacking lynchpin in the Premier League and has carried his form into Europe as well.
Salah scored seven goals in six Champions League group games, helping Liverpool qualify top of their group with a perfect record. In a group that was initially described as the 'group of death', Salah ensured that Liverpool made short work of their opponents and qualified for the knockouts in effortless fashion.
Salah looks well on course to hit astronomical numbers this season. Only time will tell if he can carry this form until the end of the season.
#1. Cristiano Ronaldo - Manchester United
Cristiano Ronaldo is nicknamed 'Mr. Champions League' for a reason.
The 36-year-old rejoined Manchester United earlier this year in a move that raised a number of eyebrows. Many expected Ronaldo to be well past his prime and approaching the end of his career.
Ronaldo silenced critics this year just like he has over the past several years, in style. The Portuguese racked up six goals in five UEFA Champions League appearances this season, scoring in every game he started.
His goals came when the side most required them and contributed directly to Manchester United topping their Champions League group. Ronaldo has shown that age is but a number and that he has aged like fine wine.
With the knockout stage in sight, Ronaldo will be looking to challenge for his sixth UEFA Champions League title.
