The German is in his second season in charge at Falmer stadium and Ayto says he has the full backing of management and the players.
He told The Argus: "Fabian has an ability to balance tactical detail with man-management. His work rate and drive are incredible and he is meticulous in preparation.
"He is equally strong at building trust and confidence within the squad. Players respond well to him because he communicates clearly and understands what motivates individuals.
"His adaptability stands out. Fabian reads games well and isn’t afraid to make bold decisions, and this has served us really well when you consider the number of goals from substitutes this season — our record is the best across the top five leagues in Europe.
"In play, he combines modern tactical thinking with a calm authority that players respect – that’s a rare skill for a coach."
