I've heard that usually peak performance for men is 33 but you can probably mitigate age related issues by training, sleeping and eating well, with some limitation, of course, as an example it'll be hard to see a 50 years old compete with a 25 who's in shape and practicing often.
33 is a peak for a regular men. Professional athletes have their peak lower (for example at artistic gymnastics athletes professional athletes retire at 17-19y.o), because they always put their body on the limit, their body exhaust more. If they were machines, then they have huge mileage. Like taxi cars breaks or die faster than regular cars Why football players retire early - probably due to muscles structure, flexibility, body recovery phases and etc.
But in sports in which your skill matters way more I would expect for athletes to last for way longer than that, as even if they are not as fast or as strong as before, they can make do and still compete due to their superior skills.
Sadly that is not about football. Football is not only about skill. Speed and reflexes matters also. Who cares if you are uber skilled, when you cant steal the ball I dont know all the details of Suarez and Duelbits deal, but I would personally go with more younger and popular player. Old school is an old school, but younger fans dont know who Suarez is. Kids dont wear Suarez tshirts, they are in Messi and Haaland today
