The Spanish guard may evade the spotlight however he remains an essential pinion in a Stamford Bridge machine chugging towards the Premier League title
For each activity there is a response and for each cause there is an impact.
In footballing terms, this reasoning of yin and yang implies that each imaginative impact and fox-in-the-crate striker must be countered by resolute and straightforward partners.
Star turns are fine and dandy, however they will just sparkle at their brightest if bolstered by a cast upbeat to work in the shadow of more renowned associates.
At Chelsea this season, Eden Hazard and Diego Costa have overwhelmed the features and stolen a significant part of the spotlight.
They have, be that as it may, possessed the capacity to flourish in the last third of the field safe in the information that midfield authorities N'Golo Kante and Nemanja Matic have their back.
Making another stride down the field and the Brazilian flair of David Luiz inside a three-man focus half unit is supplemented by the more tough qualities of Gary Cahill and Cesar Azpilicueta – two men etched out of a similar kick it, head it, square it stone as club chief John Terry.
It is these sorts who regularly sneak by the radar, with their commitment just really recognized by everyone around them.
They are, nonetheless, meriting far more prominent approval as without them turning crucial gear-teeth, a very much oiled machine would splutter and separate.
Kante has avoided the pattern with his showings through the span of the previous year and a half, with the France worldwide having some way or another figured out how to make the holding midfield part appear to be practically marvelous.
So noteworthy has he been, however, that he can never again be viewed as an unsung saint.
By definition, anybody possessing such a classification needs to work without acknowledgment, with their occupation thought to be of significant worth yet not sufficiently critical to procure the boundless recognition passed out to others.
At Stamford Bridge, with Antonio Conte sufficiently blessed to have acquired a ritzy squad which required just a minor facelift, Azpilicueta has come to characterize the model unheralded workhorse.
Gained for a unimportant £7 million from Marseille in the late spring of 2012, the Spaniard was a to a great extent obscure amount to British gatherings of people, with senior global acknowledgment just offered to him six months subsequent to connecting up with Chelsea.
That call came to fruition in the wake of settling rapidly into new environment, with the years that have taken after observing the unassuming 27-year-old turn into a handyman, and an ace of every one of them.
Sufficient to hold down a customary part on both the right-hand side and down the left, to the detriment of none other than Ashley Cole, Azpilicueta is currently working in a focal compartment and keeping any semblance of Terry and Kurt Zouma on the sidelines.
It is anything but difficult to perceive any reason why a progression of directors have been taken in by his charms, and why a man lovingly known as "Dave" by his colleagues is such a prevalent character inside a changing area that gloats significantly greater profiles and personalities than his own.
While a prevalent joke now announces that water covers 70 for each penny of the Earth's surface and Kante covers the rest, it is in actuality Azpilicueta who is included the most in Chelsea's Premier League title-pursuing mission.
No player has had more touches for the Blues this season and nobody made more passes, while Thibaut Courtois and Gary Cahill are the main different shows in English top-flight rivalry.
At the point when contrasted with the individuals who work nearby him, Azpilicueta claims best spot in various vital regions, for example, duels won, handles and captures, while he has likewise amassed less disciplinary focuses notwithstanding confronting a similar resistance and difficulties postured by said enemies.
Conte is obviously an admirer, having told columnists: "We discovered players not to adjust, but rather to assume in various parts contrasted with the past. Like Azpi, he is amazing in this new part. He is one of the best on the planet in this part."
To spread the net somewhat more extensive, the flexible protective lynchpin can likewise claim to have out-played out any semblance of Terry and Branislav Ivanovic since first connecting up with the Blues, with it wonderful to find that he is yet to make a solitary mistake prompting a shot in the best some portion of five years.
Gary Neville said of him in 2014: "Azpilicueta, when I watch him, he's as close to flawless as conceivable with regards to shielding; he's impeccable."
Jamie Carragher included Sky Sports this season: "Azpilicueta is the best safeguard in the alliance. You can discuss full-backs now being wingers. On the off chance that there was any full-back who I'd need on my group it'd be Azpilicueta, straight in."
With everything taken into account, Chelsea can view themselves as to have discovered an incredible deal and a man who will keep on displaying a level of consistency that few can coordinate while disregarding the spotlight.
