 He was an energetic, tenacious, and hard tackling box-to-box midfielder, who had a knack for committing fouls and picking up cards due to his aggressive challenges; although he was initially considered to be undisciplined from a tactical standpoint, he later demonstrated significant tactical intelligence as he matured, and unlike most defensive midfielders, he preferred to put pressure on his opponents in more advanced midfield roles and press them further up the pitch rather than mainly sitting in front of his team's defence.A tall, slender, and dynamic footballer, he was known in particular for his pace, stamina, work-rate, and passing range, which made him a versatile player, who was capable of playing anywhere in midfield; these skills allowed him to aid his team both defensively and offensively, or start attacking plays with long balls after obtaining possession.In addition to his ability to break down opposing plays, Berti was also effective in the air, which, along with his attacking drive, powerful striking ability, and positional sense, enabled him to run forward after winning back the ball, and contribute to his team's offensive play with additional goals from midfield.
