Firmino is getting ridiculous. Cut that hair, it is unwatchable.
Personally, I really don't mind long hair in footballers.
Nonetheless, I really don't understand the point of letting your hair grow long and then use those hilarious hair clips and hair bands to form those ponytail atrocities like Firmino, Bale, Moreno, Ibrahimovic etc...
If you grow your hair long, let them down like Batistuta, Nesta, Maldini et al.
