Man you can make an argument for 2012 maybe, but Real won La Liga fairly easily and also reached the CL semis like us.
In 2013 we were killed by Bayern, we got hammered 7-0
I don't think anyone can make an argument for us that year... We were generally uninspiring, we barely knocked AC Milan and PSG out.
2014?
That was like by far our worst year between 2008/09 and 2018/19 IMO. Definitely among the 2-3 worst seasons in this timespan. We lost La Liga to Atletico because we lost so many damn games against minor teams and even failed to beat them at the last game in Camp Nou. They also knocked us out in the CL. Many teams including Ateltico, Real Madrid, Bayern or even Chelsea, City and PSG had an argument over us that year.
Regardless of who won the CL, this is how I would rank us among the European elite the last 15 years or so:
2005/06: #1, at worst top 3
2006/07: top 5?
2007/08: top 10?
2008/09: undisputed #1
2009/10: maybe #1, definitely #2 at worst
2010/11: undisputed #1
2011/12: top 3
2012/13: top 3
2013/14: top 5
2014/15: undisputed #1
2015/16: top 3, maybe even #2 or even #1
2016/17: top 5
2017/18: top 5, maybe top 3
2018/19: top 5, maybe top 3
2019/20: top 10
2020/21: top 10
2021/22:
