Few teams change systems from game to game as seamlessly as Thomas Frank’s Brentford do.
When facing one of the Premier League’s bigger sides this season, they have used 3-5-2. For everyone else, they have used 4-3-3.
It is a pattern to which they have stayed true, switching from a back three to a back four depending on the strength of the opposition.
But the defensive set-up is not the only important distinction between these two systems. It is equally as significant that they either use a front two or a front three.
