Brentford are unbeaten in five and Chelsea have scored 15 goals across the same span. Friday night's west London derby brings two confident attacks together at the Gtech Community Stadium.
A derby with attacking intent
Neither side arrives short of belief. Brentford have found a way through every recent test, while Chelsea's latest five matches have produced 25 goals at both ends.
That makes this more than a neighbourhood argument. It is a test of whether Brentford's steady momentum can withstand visitors capable of changing a match in a burst.
The Bees keep finding answers
Brentford's five-match unbeaten run contains two cup wins and three Premier League draws. They scored six at Birmingham City, edged Reading 2-1 on Tuesday and shared the points with Leeds United, Sunderland and Bournemouth.
Twelve goals scored and six conceded is a healthy balance. The draws also show that Brentford have stayed in matches even when they have not found a winning moment, a useful habit before a derby likely to shift quickly.
Chelsea matches have been breathless
Chelsea have won three of their latest five matches, including a 4-3 league victory over Brighton and a 6-3 Carabao Cup win against Leeds United. They also beat Luton Town 2-0 before losing 2-1 at Arsenal and drawing 2-2 with Hull City.
Fifteen goals in five matches gives the visitors obvious attacking weight. Ten conceded across the same run leaves room for Brentford to believe they can make this an uncomfortable evening.
Who controls the chaos?
The strongest version of Chelsea can overwhelm opponents with the number of chances it creates. Brentford's task is to make sure the match is not played entirely at that speed.
The Bees have scored in each of their latest five and will expect opportunities of their own. If they stay composed when Chelsea surge forward, the Gtech crowd could have a proper derby to drive.

What to watch
Brentford's unbeaten run has been built on persistence; Chelsea's recent form has been built around goals. The decisive question is whether the hosts can keep their shape without losing the attacking ambition that has carried them this far.
