Real Madrid Played 7 teams in the champions league and lost to 4 of them. 4 different teams.
We lost 3 games in 38 to Win the Premier league. Anyone who thinks the Champions League is harder to win is talking absolute bollocks.
That's the nature of the competition. A European away game is really tough to win. Pep's Barca, the greatest club of all time had a terrible record in European knockout away games.
Regardless of the number of games, the competition for the PL was only ever between City, Liverpool and Chelsea, and towards the end just between City and Liverpool. Real Madrid defeated all 3 PL sides over 180 minutes to win the CL. That's harder.
