There has never been a greater focus on tactics than there is today. Gone are the days of just 4-4-2. Last season Manchester City won the Premier League playing 4-3-3 and Chelsea won the Champions League playing 3-4-3.
At Euro 2020, England used both systems in reaching the final. The modern-day player is an intellectual with an understanding of how to play in different systems, whichever way his manager wants.
This interest in football's tactical side has filtered through the game. Arsene Wenger once told me he saw a Sunday League manager with a flipchart while cycling through Barnet on a rare day off!
