Graham Potter's Brighton team were predictably unpredictable when playing against Brentford last season. The 47-year-old was typically flexible across the two games and played with at least two differing systems for the home and away matches.
That's standard Potter and the sort of tinkerman antics that Chelsea will have to get used to. Their team at the weekend Vs Aston Villa was just as fluid. Although the base shape of a 3-4-3 remained, players moving across the pitch made the matchups tilt in the Blues' favour in the end.
With just three days before the trip to the Brentford Community Stadium, not much of an away game though it must be said, Potter has some key decisions to make going into the match with one eye on playing Manchester United on Saturday too.
