Sometimes an old athlete may want to come back for some special match. Some bettors might still bet on him despite of old age and lack of recent experiences in the sport. That is because of what we call nostalgia. They might recall the past memories or past performances of the athlete that may not necessarily reflect the recent performance of the athlete. So be careful when betting because you might just be nostalgic.
I don’t even feel hyped up when I see an old althlete coming back to the pitch to play - sometimes if you engage in discussion with your fellow fans you’ll see that they too are of the same opinion that the player won’t do as much as people are hyping them up for.
To me, I would rather bank on a player who’s doing well then to place my hope on an old player, if they had good form I can still consider them but those who haven’t played for a long time but them just pop out of nowhere that they want to play or that they’ll be playing are definitely not going to be among my top pick.
