Egyptian star Mohamed Salah, the Liverpool player, posted a mysterious message on his Instagram story on Wednesday evening while reading a book by Swedish author Thomas Erikson titled "Surrounded by Fools." Salah has experienced a tough period in recent weeks after clashing with his former coach Jürgen Klopp on the touchline last month, while some critics believe that his decline in performance was one reason for Liverpool's drop from first place to third in the final stretch of the English Premier League. Salah has often shared the books he reads, having previously posted a picture of himself reading "The Subtle Art of Not Giving a F*ck" by Mark Manson. Erikson published the famous book "Surrounded by Fools" in 2014, which aims to first understand oneself and then understand different personality types and how to communicate with them. The book categorizes these types into four colors: red, yellow, green, and blue. The book became widely popular among hundreds of thousands of Swedes who bought it upon its release, but several Swedish scholars opposed its content, arguing that the author lacks fundamental knowledge in psychology and behavioral sciences.
