Match officials do not referee differently despite VAR's presence, says Darren Cann. He retired this month after over 1,000 games as an assistant referee. Cann views VAR as a valuable tool and aims to make the right decisions to minimize its use. The introduction of semi-automated offside has made offside calls quicker and easier. Cann has faced challenges keeping up with the modern game's speed and complexity. Before and after games, he has specific preparations for improvement.
