Meanwhile while some mentioned who vs who scored against, he're my CL table updated.
Note that the number of assists of Messi varies greatly from the sites I looked, from 24 to 34 (!), I have no idea why. Ronaldo seems to be around 40 to 42.
I guess because they are not "official" it varies according to the definition of that site.
In this I used Transfermarket site that lists both the high numbers of assists I've seen for both players.
I don't have the assist information but it would be great to check the numbers and add the club against too.
Assists in the CL:
Messi 34 in 124 apps (0.27 assists/app)
Ronaldo 42 in 149 apps (0.28 assists/app)
Goals scored in CL:
Messi 100 in 124 apps (0.81 goals/app)
Ronaldo 119 in 149 apps (0.80 goals/app)
Messi has 60 goals in the group stages (60%) and 40 (40%) in the knockout stages.
