Conor Washington has never got the better of Brentford boss Dean Smith.
Now, the QPR striker plans payback time after an arid spell when the two crossed swords in the past.
This will be the pair's first head to head since they moved to their new clubs.
But when the Northern Ireland international was at Peterborough and Smith was Walsall gaffer - it was all Saddlers as far as wins go.
In six meetings since 2013, the best Posh and Washington could manage were draws. There were four of them and two defeats rest and free-scoring Washngton failed to score in any.
Factor in Romaine Sawyers at Walsall and now Bees, and striker Scott Hogan when he was at Rochdale, and Washington needs to break the spell.
“Hopefully I’ll be able to put that record of not scoring against Dean Smith to bed early doors,” he said.
“Romaine was brilliant in the games I played against Walsall and is one of Brentford’s big threats.
“And Scott who I played against at Rochdale is a top-class player scoring goals for fun.
“Brentford have top players but so do we, so we will be looking to negate their threats and put our own stamp on things.”
After a dismal 2015-16 record in the London derbies with both the Bees and Fulham, Rangers are at least buoyed by their recent win over the latter in the first bid for bragging rights.
Given that success Washington is aiming for a clean sweep this time around.
“The win and the performance in the Fulham game was really important for us,” he added.
“So now we want a perfect record when it comes to London derbies this year as it is something we haven’t had for a while.
