Chelsea are back to their cynical, deceptive best - or worst.
Jose Mourinho has been back at Chelsea for a matter of months, and whilst you can't teach old dogs new tricks, Chelsea's recent performances have shown you certainly can teach old dogs old tricks.
Against a lacklustre Arsenal last night, Chelsea displayed all the gamesmanship and guile you expect of a Mourinho side.
At one point in the fixture, as the clock ticked down and Arsenal chased a comeback, FOUR Chelsea players dropped to the deck, feigning injury, disrupting the Gunners' play and wasting precious minutes.
It was the epitome of Mourinho's Chelsea - re-born.
The Portuguese hasn't saved this unsavoury approach to football for his spells at Stamford Bridge, however.
His major successes at both Porto and Inter Milan were built on distinctly Machiavellian undertones.
Even at Real Madrid - a club famed for their attacking intent, and currently possessing one of the world's best attackers - much of his stint was forged on conflict.
Invariably one of football's top tacticians and man-motivators, Mourinho is one of Europe's top coaches.
But for Mourinho, the end always justifies the means.
Cheat to win? The key word is 'win' and any predicator is irrelevant - at least according to the self-proclaimed Special One.
As Arsenal's technically superior midfielders skipped past their stronger opponents last night, any progress was quickly halted by a crafty swipe of the legs or aggressive tug of the shirt.
And certainly in Mourinho's last spell at the Bridge, Chelsea were known for the verbal pressure they put on referees.
Ashley Cole, Frank Lampard and ring-leader John Terry are masters of the the art of skulduggery.
Last night reflected perfectly what Mourinho - and Mourinho's Chelsea - are about.
They will win. Often.
And they will use every trick in the book to do so.
And as four of the away side lay in 'agony' at once last night, it was apparent, Mourinho's Chelsea are well and truly back.
