It's a very rare occurrence when a side lets a world-class player walk out their doors and doesn't suffer any detrimental consequences.
For the most part, when a side parts company with one of their best players, what generally follows is a slump in form followed by a re-structuring of the playing style to adapt to life without a key figure.
When you have a side as star-studded and talented as Real Madrid's is at the moment however, that rule doesn't necessarily apply.
Mesut Ozil's move has caused chaos in abundance at Los Blancos, with clusters of high-profile players publicly disagreeing with the sale, and a large proportion of supporters unconvinced that his move was the correct decision for the clubs future.
As a Madrid fan, I too was initially sceptical about the decision to sell a 24-year-old playmaker who arguably already one of the best in the world at what he does.
After allowing the realisation to sink in however, you can begin to see perhaps why the decision was sanctioned to allow him to leave for Arsenal, aside from the obvious attempt at recouping from the obvious deficit encumbered as a result of purchasing Gareth Bale.
Madrid are never going to be left bereft of world-class personnel whilst Florentino Perez remains as president, his commitment to the Galactico regime makes sure of that. However it can result in a scenario wherein there are, and I understand this sounds strange, too many top quality players for one side.
Such a predicament rarely harvests harmonious results, with high-profile players getting the hump from lack of playing time, genuine talents being frozen out of action and the development of starlets deemed mature enough for first-team football hindered.
At Madrid there are currently as many as eight top-class midfielders vying for positions in a starting XI that usually only has room for five. Xabi Alonso, Sami Khedira, Luka Modric and Asier Illarramendi are all fighting for allocations in the centre of midfield. Add to that the figures of Angel di Maria, Isco, Cristiano Ronaldo and, of course, Gareth Bale, and you can begin to see a squad where strength in depth veers steadily towards being more a problem than it is productive.
Mesut Ozil is, and will continue to be, a world-class act, but his departure from Real Madrid will not prove to be one that shakes the foundations of the club.
On the contrary, it should allow new signing Isco, who it must be said has made an excitingly brilliant start to life at the Bernabeu, to flourish without having to worry too much about being sidelined. The move will also free up Ancelotti in terms of the undoubted pressure from the fans who will expect to see Bale and Ronaldo tearing down either wing.
Ozil's exit, though disappointing from a footballing point of view and perhaps ludicrously foolish at first glance, could prove to be ultimately beneficial for Los Blancos.
As highlighted in my prior article about the way the Galactico regime is structured, no one bar Cristiano Ronaldo - and now perhaps Gareth Bale - is truly safe at Madrid.
