It was all sunshine and rainbows for Chelsea fans on this day in 2009, as a 4-1 victory over Arsenal away from home put away any doubt who was the best London team.
The Blues made sure that Arsenal couldn't catch them to a third place finish in the Premier League with goals from Alex, Nicolas Anelka, a Kolo Toure own goal and Florent Malouda sending the away end into ecstasy.
Nicklas Bendtner was able to climb over Michael Essien and head a consolation goal in past an unassuming Petr Cech but it wasn't enough to get the Gunners going as their home fans filtered out of the Emirates with their heads down.
Blues domination throughout
Chelsea's pure passing ability was on full display, as the Brazilian Alex thundered home a header off the crossbar to give Chelsea the lead from a Didier Drogba free kick in the 28th minute.
Nicolas Anelka thundered a 25-yard strike into Lukasz Fabiański's bottom corner against his former club not long after, humble in his celebrations after having diced up the Arsenal defence.
Arsenal were being given a lesson in clinical finishing, after having had the majority of shots in the first half, but were unable to convert against a top-form Cech.
It went from bad to worse for the Gunners as centre-back Kolo Toure wrong-footed former teammate Ashley Cole's cross into his own net, but Nicklas Bendtner did grab a goal back for his side.
Arsenal were rallying but the game was put to bed in the 86th minute when Florent Malouda wrapped up the win after Anelka's shot hit the post.
Chelsea secured a top three Premier League finish and entry into the next season's Champions League group stages with the win, having been eliminated by Barcelona in heart-breaking fashion three days prior.
Despite the result, the Blues would go onto win the F.A Cup, for the fifth time, against Everton 2-1 in their final game of the season.
As for Arsenal, the loss meant a comfortable fourth place finish in the league, nine points behind rivals Chelsea but nine ahead of Everton in fifth.
