Highly-anticipated consecutive Clasicos could attract an audience of over 350 million, with the second-leg of the CL tie as the main attraction
The tradition of rivalry among both teams, the matchday & kick off time of the game, the type of broadcasters that hold rights of each game globally, the international reputation of the tournament and the city where the game takes place are just a few of the factors that were taken into account to predict the possible audience of each game.
Saturday's league match could attract up to 78m viewers as the clash loses value because of the importance of the meeting as the outcome isn't likely to affect the title race.
Wednesday's Copa del Rey fixture is expected to be viewed by 77m due to the lower reputation of the tournament and also with the final taking place on neutral terrain.
The second-leg of the Champions League semi-final could reach as much as 100m viewers globally, as the tie will most likely be decided on May 3.
However, the audience could be lower if one of the two teams records a big win in the first leg on April 27. 91m viewers are expected to tune in to the first leg due to the fact that there will be a return game the week after.
