#1 Lionel Messi (Barcelona)
Like Cristiano Ronaldo, Lionel Messi has totally reshaped the footballing landscape with his performances over the course of his career.
The Argentine maestro enjoyed a period of almost unfettered dominance between 2009 and 2012, winning the Champions League Golden Boot in each of those four seasons consecutively and broke Raul's previous record of 71 Champions League goals first, but he had to take a backseat as Ronaldo emerged as an unstoppable force on the continent in the latter stages of his Real Madrid career.
Messi finally gained sole ownership of the Champions League Golden Boot last season, as his 12 goals were significantly more than anyone else managed, but the prize came at a bittersweet cost, as his goals failed to inspire Barcelona to the Champions League.
With 112 goals, Messi is unsurprisingly the second-highest goalscorer in the history of this illustrious tournament, and he would be seeking to win his sixth Champions League Golden Boot while hoping his goals count for something on the collective level this time.
