Because we're not Celtic in freaking Scotland, we're Barcelona and we compete the league against Real Madrid and Atletico, we're not winning 10 league titles in a row against the biggest club in the history of the sport, are you in grasp with Reality?.
6 out of the last 9 seems like a fair deal to me, call me when Ronaldo wins 6 leagues out of 9 against Real Madrid.
Juve are in a 7 league title streak, Bayern are the German juggernaut, they're still 1 and 5 titles behind Real Madrid, nevermind including the 13 UCL titles.
We had "the dream team", they won 1 European Cup. Real Madrid won 3 in the next decade fielding a bunch of mediocre players. You seem to lack grasp of what competing against Real Madrid is like.
Messi in his 50 goal season: 1.35 goals per game
Ronaldo in his 48 goal season: 1.37 goals per game
What does the distance covered by Messi have to do in this, are we talking about football, the game you kick a ball and try to win by helping your team score or don't get scored, or are we talking about decathlon?.
