I'm sorry but that's not fair at all. He makes up for not playing defense by having every attack go through him. It's not like he's sitting in the box waiting for a tap in. He starts his plays from the middle of the field and most of the time he's at the end of the play assisting or scoring with explosive sprints with a lot of physical contact from defenders. That's super hard on your stamina at any age, especially 33.
He might have the best left foot in the game, his brains might weight 15 kilos and so on, but it's a physical sport, where you need a certain physical condition in order to play and Messi clearly isn't capable of doing it anymore, considering how fast and physical game is nowdays. All the top teams in the world are either great at counter attacking, great at pressing because that's how you keep up the tempo. Barcelona do not have players for anything, they're bunch of fossils walking around the field and hoping their 80% posession wins the games in La Liga against Getafes etc, as it has done because they still have way more quality in there but if they're facing team like Liverpool, City, Bayern in the CL, they can't have 80% posession and they're required to run way more and since no real counter attacking ability or anything, they basically become useless. Even the last few classicos against RM they've looked like bunch of amateurs compared to RM. That whole Barcelona team is built by playing with quite low tempo, that's why Messi is able to jog around like he does and it's a cold hard fact. Let's say couple years ago when those players were still somewhat on their early 30s, not 33-34s they were just fine, but that couple years in there with no real additions to their team and couple La Ligas when RM was putting all their eggs to the same basket(CL) just made them believe we still got this, even the reality is that they don't and it's crystal clear nowdays.
