Prime Messi was 2014/2015.
This myth that United got beaten by prime Messi/Barcelona needs to stop. They lost to Chelsea and Inter FFS.
Also the Messi of 2011/2012 (when they got knocked out by Chelsea) was better than the Messi that beat United.
United have been historically poor in Europe compared to domestically.
Compare this to Liverpool who reach a CL Final every 2-3 seasons that they are actually involved in since CL started.
2006-2007 Semi-final vs Milan
2007-2008 Champion vs Chelsea
2008-2009 Final vs Barcelona
2009-2010 Quarter-final vs Bayern
2010-2011 Final vs Barcelona
That's a team that did 3 finals, won once and 1 semi-final and 1 quarter-final in 5 years.
That team was doing well.
For Barcelona, we see:
2006-2007 R16 vs Liverpool
2007-2008 Semi-final vs United
2008-2009 Champion vs United
2009-2010 Semi-final vs Inter
2010-2011 Champion vs United
After that, they do semi-final x2, QF, and then the last title vs Juventus.
Are you really saying that was not peak Barcelona then? And isn't peak Barcelona correlated to a peak Messi?
Or is Messi only on the peak when he doesn't play United, because no way United could have beat them or anything? What is that logic really?
We did very well during those 5 years, and Barcelona was doing fine as well.
