Brentford and Queens Park Rangers meet at Griffin Park on Saturday with the Bees going for a double, while Rangers eye that win needed to maintain their Championship status.
The two sides met in October at Loftus Road under the lights in front of the Sky cameras and it was Dean Smith's side who claimed victory thanks to goals from Josh Clarke and Romaine Sawyers.
The Bees have not done the double over their west London foes for 52 years and, for the second successive year, will finish above their rivals from Shepherd's Bush.
That said, bragging rights are at stake and both sides will be doing their utmost to give their supporters a chance to one-up their rival fans in the workplace, at school and down the west London public houses.
Below, GetWestLondon outline how the two sides have changed since the last time the two sides have met six months ago.

Brentford have gone from a side that was reliant on Scott Hogan for goals to a team where goals can come from all areas on the pitch.
The Bees lacked wingers during the first half of the season and had to try and pass through the middle to break opponents down.
That had some success but, more often than not, if Hogan failed to fire then the Bees were unlikely to cause serious concerns to teams.
Dean Smith and the recruitment team changed that in January by recalling Jota from Eibar as well as signing Florian Jozefzoon and Sergi Canos from PSV Eindhoven and Norwich City respectively.
That trio now have 15 goals since January 1 with Jota contributing 10, Canos four and Jozefzoon opened his account at Barnsley on Monday.
Hogan's departure to Aston Villa also led to a change in personnel up front with Lasse Vibe now leading the line.
The Dane, who entered January on two goals, now has 14 in the league plus a goal against Eastleigh in the FA Cup.
While Hogan was more of a predatory finisher, there were several games where he made little or no impact. Vibe, on the other hand, is a hard worker and has helped create space for others to thrive.
Brentford now have a specialist left back available to them after Rico Henry and Tom Field returned to fitness.
At Loftus Road, centre back Andreas Bjelland was playing at left back and he shared the role with fellow central defender Yoann Barbet for a period after an injury to Callum Elder, while Henry and Field were also on the treatment table.
The presence of Henry and Field have provided more balance to the side and there has been a noticeable improvement in that area of the pitch.
Romaine Sawyers has also improved from October and he is one of the club's most creative outlets.
There is no doubt that the Bees are a more balanced and creative side than they were back at Loftus Road in October.
How have QPR changed?
The obvious place to start is the change at the top with QPR sacking Jimmy Floyd Hasselbaink after the 1-1 draw at Nottingham Forest the following week.
For many at the club, the decision to part company with the Dutchman stemmed from the home defeat to the Bees, much like a loss at Griffin Park 12 months prior led to the downfall of Chris Ramsey a game and five days later.
So current boss Ian Holloway may need to watch his back if his side go down at Griffin Park.
QPR were active in the January transfer window, signing three players on a permanent basis in Sean Goss, Luke Freeman and Matt Smith from Manchester United, Bristol City and Fulham respectively. They also brought in Kazenga Lua Lua and Ravel Morrison on loan.
Going out the door were Sandro, Sebastian Polter and Tjaronn Chery while Ben Gladwin and Ariel Borysiuk left on loan.
QPR's form has been mixed since the January transfer window. They went on a run where they won five games in seven, losing at Preston and drawing at Leeds but are currently on a run of five straight defeats.
Holloway has been tinkering with his team in recent weeks, making a host of changes for each encounter.
The impression coming out of the club in the summer is there is likely to be another rebuild to have a tilt at the play-offs.
The club have not been stable in Tony Fernandes' stewardship and they need some form of stability to get things right.
Will Holloway be given that chance? He's already lost as many games as Jimmy Floyd Hasselbaink did in his year in charge.
Crucially though, Holloway still has the fans' backing which was something his predecessors never had.
