Messi scored 14 Champions League goals in 11 appearances in 2011/12; Ronaldo scored 17 in 11 in 2013/14. With the same appearance count, Ronaldo leads both the total and the per-appearance rate: 1.545 against 1.273.
Why the 11-match setting matters
The calculator starts at 11 appearances, reproducing the actual 14 and 17 totals. Move the slider to see how the same rates scale. Changing the number of appearances cannot change which rate is higher; it changes only the size of the calculated gap.
What the comparison leaves out
Only the Champions League main competition is included. League goals, domestic cups, qualifying matches and penalty shootouts are excluded. Equal appearances do not mean equal minutes or opponents, and goals alone do not measure chance creation or the entire contribution to a team.
