The hangover of the 2-0 victory by Chelsea over Arsenal will still resonate clearly in many football fans minds.
The skill, power and sheer dominance of Chelsea over their supposed title rivals was apparent for all to see; the result never looked in doubt.
However, the most powerful and prominent factor I took away from the match was that Chelsea now have an ability to be efficient and ruthless against all sides.
Last season against the stronger teams i.e. Manchester City they worked like a machine, nicking a goal and then falling back to their 18 yard box with all eleven players behind the ball.
In that match Chelsea were effective, yet lacked any sort of dominance. Yes they won, but Man City had walked all over them in other areas. City had 65% possession to Chelsea's 35% showing that Chelsea lacked power in the game.
However, although the three points were the same, the power and dominance that Chelsea showed against them was incredible. This was a well-drilled Arsenal team, far superior physically and mentally to the one that Chelsea humiliated last season, a team that had recently defeated Galatasaray 4-1 earlier in the week and had drawn with City as well. Yet Chelsea managed to combine 3 key elements:
They worked like a well-oiled machine always looking threatening in attack and never threatened in attack. They played this game as though Arsenal were a mid-table side, establishing a game plan and sticking to it.
Again like against City last season, Chelsea had less possession, but to a much lower extent with them having 47% possession throughout the match. However, this statistic looks irrelevant seeing as Arsenal did not managed a single shot on target through the entirety of the match.
This shows that though Arsenal had most of the ball their attacking efforts were stifled and ineffective against Chelsea's defence. This shows how Chelsea didn't allow Arsenal any space to move or pass, frustrating them throughout as seen by Welbeck’s two footed challenge on Fabregas late on in the match.
Yes, Welbeck the same striker who had scored a hat trick midweek, but had not managed a single shot on target throughout the entire game.
Arsenal were simply dominated by Chelsea's resolute defence and Costa's predatory link up with Fabregas.
Dominance and Efficiency count for nothing in big games, if when presented with chances, those chances aren't taken. And yes Chelsea were ruthless, Chelsea had just 5 shots throughout the match and they scored with 2 of them.
Costa's ability to finish combined with the midfield maestro of Fabregas allow for clear-cut chances to be taken.
These 3 factors were all there against Arsenal showing what a monster this new-look Chelsea side are. They share these 3 things with the 2003-04 Arsenal side that went undefeated throughout that campaign.
Can Mourinho take Chelsea to those heights, even surpass them? If Chelsea continues to show their class and follow the clever guidance from Mou then I don't think we could be talking about the 2014-15 Chelsea invincible s for year to come.
