Friday was known for giving his all in any game in which he played, no matter the circumstances. Hurley later said that Friday would often become furious at his teammates for not trying their best, even in training. This strong drive to always win even extended to the use of physical intimidation to unsettle opposing players, leading contemporary critics to label him a "villain". Friday also employed the use of psychological tactics; aiming to spook opposing players, Friday would kiss them or fondle their testicles. Cardiff teammate Paul Went recalled that these tricks would "completely " defenders and affect their concentration. Although he was often criticised for the number of bookings and sendings-off he received, Friday believed he was justified to chase victory by any means, explaining his attitude in a 1977 interview: "On the pitch I hate all opponents. I don't give a damn about anyone. People think I'm mad, a lunatic. I am a winner".
