What is Lionel Messi's, Cristiano Ronaldo's and Diego Maradona's goals per game ratio against european cup/champions league winners?

Question

GOAT debate

According to the GOAT debate Pele was unproven against European clubs, yet in the Intercontinental cup Pele scored two goals in the 1962 Intercontinental Cup first leg at home to European champions S. L. Benfica. In the second leg he hit a hat-trick on Benfica's home turf taking his tally to five goals in two games against the European cup winners.

In the first leg of the 1963 Intercontinental Cup Pele scored another two goals on European cup winners A. C. Milan's home turf, though he did not score anymore in the return leg nor replay, taking his total to seven goals in five games against European cup winners.

Pele also failed to score in the 1968 Intercontinental Cup final against Inter Milan, making his total against European cup winners only seven in six games.

Pele also scored a single goal against arguably the greatest team in the world at the time, Real Madrid, on Real's home turf, making his total against European cup winners eight goals in seven games.

Question

So my question is, for those interested in the notable GOAT debate that argue that Pele never proved himself against the best sides in Europe, how many goals have his GOAT competitors, Lionel Messi, Cristiano Ronaldo & Diego Maradona each scored against European cup winners (UEFA Champions League) and is their goal per game ratio against European cup winners (Champions League) better than Pele's?

P.S

It only applies to the following:

(a) games against whoever were current European cup/Champions League winners at the time of game being played.

(b) games against whichever team went on to win the European cup/Champions League the same season the game was played.

(c) In the instance that the team they played for won the European cup/Champions League, then I will accept games against the runners up, from either season cup was won, or season following.

This is not an easy one and will require a lot of researching and going through the players fixture lists, but there is 50 bonus points available for whoever proves that Pele is or is not the GOAT when it comes to goals per game against european cup/champions league winners/elite european clubs.

Also there were a couple of seasons when Real Madrid defeated Atletico Madrid in the final. For those seasons Atletico Madrid count as european cup winners from Cristiano Ronaldo's perspective, but for Lionel Messi, Real Madrid are the european cup winners.
