Hayden is arguably the worse offender of the two, as he has been booked six times in 11 starts, while Bellerin has been booked six times in 15 starts.
He has been booked in each of his last two games against Liverpool and Sheffield Utd.
Bellerin, meanwhile, averages a booking every 213 minutes.
The Spaniard, too, was booked in his last game when Arsenal defeated West Brom 4-0 away from home.
Thereafter, there is a group of players who have received five yellow cards this season: Jonny Evans, Oriol Romeu, Abdoulaye Doucoure, N'Golo Kante, Kalvin Phillips, Yves Bissouma, Conor Gallagher, and Matty Cash.
Out of that group, the players who have the worst booking-per-minutes ratio are Evans and Gallagher.
Evans has played 1,160 minutes in the Premier League this season, and averages a yellow card every 232 minutes.
Gallagher has played the exact same and has the same average.
Though the players on six and five bookings have a slight issue with indiscipline this season, with all of them having been suspended due to their tally of yellow cards, only one has actually been sent off, Bissouma.
In only the second game of the season, the Brighton midfielder saw red for a ridiculously high boot sent into the face of Jamal Lewis.
