As Bruce Buck shook the hand of Serbian giant, Nemanja Matic on Wednesday evening, Chelsea's filled-to-the-rim midfield expanded further.
With the imminent departure of Kevin de Bruyne to German outfit Wolfsburg, that will leave 11 midfielders fighting for a ridiculously competitive spot in Jose Mourinho's top-heavy starting line-up.
Chelsea may have finally found the solution to the problematic defensive midfield position, arguably never properly filled after the void left by Claude Makelele's exit to Paris Saint-Germain back in 2008.
The 6ft 4in 25-year-old, since swapping London for Lisbon as a makeweight for the transfer of David Luiz three years ago, has evolved into perhaps one of the best holding midfielders in Europe. He has even drawn comparisons with Ivorian powerhouse Yaya Toure.
Matic has the extraordinary gift of being not only defensively tight, but, when given the freedom, can often be seen venturing forward with much confidence, like that of a natural attacking midfielder.
While talented in the air, he also knows how to use his strength, pace and awareness when needed. In a 2013 fierce match-up with arch-rivals FC Porto, Nemanja Matic scored a spectacular volley from the edge of the box, which came second in the FIFA Puskas award - given for the best goal in the world in the last calendar year, a fantastic achievement.
Matic should fit into Chelsea's style almost effortlessly, due to his immense work rate, something Jose Mourinho publicly admires, his versatility to play effectively in different formations and just his overall passion, drive and love of the beautiful game.
Tactically, he would give Ramires or Frank Lampard (his partner in the holding role) the much-desired freedom to roam forward where they both perform so effectively, due to Matic's solidity and defensive reliability.
As an added bonus, he would be a valuable asset to set pieces (both offensively and defensively) because of his height and monumental stature - lots of Chelsea goals this season have come from set-pieces.
Again, if needed attacking-wise he is more than capable, having pace and a surprisingly high amount of agility and energy, offering Chelsea something new in attack, similar to the role the aforementioned Yaya Toure plays at Premier League rivals Manchester City.
There is no doubt that this return to Stamford Bridge will be a happier one and if used effectively by Jose Mourinho, a successful one too.
