What I dislike about players' autographs is the they are, in the main, totally illegible, just a squiggle. I had a colleague, now deceased, who had an autograph book of pre-war players and showbiz folk, and they were all well and carefully written. Now they just get a marker pen and smear a couple of marks. I bought a City calendar a couple of years ago or so and each month had a photo of a player with his autograph. They were quite unreadable and meaningless. I was shocked.
I'm sure it's not just footballers - I saw Andy Murray coming off court the other day and he "signed" a couple of autograph books with what was clearly a couple of stripes.
Take a bit of trouble, you disrespectful morons.
