#3 First player with 100 goals in three leagues
In addition to the previous record, Ronaldo could also become the first ever player to score 100 goals for clubs in three of Europe's top five leagues.
There are a few players who've managed over a century of goals with clubs in two different leagues - Zlatan Ibrahimovic, Gonzalo Higuain, and Edinson Cavani - but none has done it in three.
Ronaldo has maintained a prolific goal-scoring record since leaving Sporting CP, netting 108 times for Manchester United, 450 for Real Madrid, and now, 68 for Juventus. So it's only a matter before he hits triple digits in Italy as well.
#2 Golden Boot in three of Europe's top five leagues
Ronaldo's scoring record with Juventus might be stellar, but the Golden Boot has, unfortunately, eluded him so far. He came fourth in the 2018/19 season and was eclipsed by Ciro Immobile last time in the race for the Capocannoniere.
The Portuguese ace will definitely have his eyes on the prize once again, and if he's third time lucky, then he'd be the first ever player to finish as top-scorer in three of Europe's top five leagues.
As you may know, Ronaldo has won the Golden Boot in the Premier League once (2008/09) with Manchester United, before picking up three more at Real Madrid (2010/11, 2013/14, 2014/15) in La Liga.
#1 Highest appearances in the Champions League
His favourite competition, Ronaldo is often called 'Mr. Champions League' for his imperious exploits in Europe's premier club tournament over the years, breaking records after records in it.
He's the all-time highest scorer, has finished as the top-scorer on most occasions, has made the most assists, has scored the most free-kicks, has scored the most goals in the finals, and so on.
This season, he could reach another important milestone - with just eight more appearances, Ronaldo (170) can beat his former teammate Iker Casillas (177) for most matches played in Champions League history.
