I am very serious
Xavi was great in his last year, played far too little then. But I guess it worked out that year, the year(s) after wasn't as great though... He's one year older than Zlatan and with a physique that should be less hampered by age. I think his time is up now though, not least because he stopped playing.
Alves mostly because the alternatives never were so great. I am sure he'd combine as well as before, put some brilliant crosses and passes, and still defend and run decently. He played 30 games in Brazil last season I see...
Iniesta got a little lazy in the last years, but 30min now and then would be useful in 2021 surely.
There always comes a time when you need to get rid of your stars, and the best time is often earlier than you'd think, but in the case of Barcelona, knowing the terrible replacements, I think these three players would've improved play still.
Though what does it matter, no way to prove it (or disprove it). The only thing to do is laugh...
