Jose Mourinho's recent FA charge for improper conduct will be an nuisance to him but he won't be too worried about it because it is difficult for managers to get annoyed when their team is purring.
That is precisely what Chelsea are doing at the moment and their last two victories will only have served to increase the Portuguese's famed self-confidence in the title race.
Cardiff City were given a sliver of hope when David Luiz misjudged the pace of a pass and let in Jordan Mutch to open the scoring, but the Blues could not be held back and however unfair the equaliser was, the way they took the game away from the newly promoted side can leave no argument as to whether they deserved it or not.
Samuel Eto'o opened his account for the Stamford Bridge club against the Welsh club and looked much sharper, while everything looked a bit more fluid.
That victory took them to second in the Premier League behind Arsenal, but it was the very impressive win over Schalke in the Champions League on Tuesday that really gave an indication of how much Mourinho has the team closing in on its best form.
Fernando Torres took the plaudits for scoring twice and looking a little like his old self, but it was the solidity at the back that really impressed Mourinho in the comprehensive 3-0 victory in the Veltins Arena.
Chelsea went over to Germany and despatched a talented Bundesliga side in an ominously professional manner - ominous for their Premier League rivals that is.
A Mourinho side that is looking extremely solid at the back away from home is one to be feared; that sort of performance harks back to his first spell at Stamford Bridge and the all conquering physicality they possessed.
This is a very different Chelsea side but the mentality looks like it has returned, an iron will when in a tough contest and the belief that they will eventually prevail against most any opponent.
Eto'o and Torres both finding the net and looking like hitting a rich vein on form is perfect for the squad as it means competition for the centre-forward spot will be dictated by confidence, not the fear that had riddled them for so long this season.
When one cannot find a breakthrough Mourinho need only turn to the other, knowing he is in the groove, hungry to impress and ready to make a stake for a place at the top of the starting XI pecking order.
Arsenal have been leading the way up to now, but their defeat to Borussia Dortmund showed a naivety, acknowledged by Arsene Wenger, that could well scupper any tilt at silverware if not properly unheeded.
You just can't see Mourinho's side making the same mistake when in a similar situation and even less so when they are firing on all cylinders as they build momentum through the season.
Chelsea's squad, with the exception of Manchester City's, seems so much more polished than that of the current closest rivals to them in the league, who all appear to be just a touch too inconsistent.
Sunday's meeting with the Citizens at Stamford Bridge will be a crucial clash and a significant indicator as to who of the pair will be leading the charge to the Premier League title.
Betting against Chelsea at home is always a risky ploy and Mourinho looks like he is finally getting his team to operate as he wants them to.
The rest should be worried at such a prospect, very worried.
