Today will see Chelsea splash out around £21 million on the type of player they thoroughly need. A box-to-box midfield player both technically gifted and strong in the tackle - he is the perfect player for 'the Jose Mourinho' philosophy.
Like Costinha, Claude Makelele, Esteban Cambiasso or Sami Khedira before - Mourinho always has one unfashionable player among his midfield - there to provide the canvas for the artists ahead of him.
But that player is Nemanja Matic - who they let go as part of a swap deal just three years ago.
But if the other big teams in the Premier League had a ‘Matic Moment’ … who would it be?
Who would Tottenham Hotspur spend big on now, that they let go so cheaply years ago?
A few come to mind. Firstly, from just a few months ago, letting Steven Caulker now seems like a mistake. But they were well compensated for his departure - so we doubt Daniel Levy and co are overwhelmed with melancholy.
Giovanni Dos Santos also springs to mind. He has been superb since leaving for Mallorca and now Villarreal. But they did not get rid of him so much as he forced a move.
What about Gary Hooper? A natural finisher they kicked out at the age of 14 - certainly a good shout.
But the one that sticks out is Kevin Prince-Boateng.
The young German-Ghanaian signed for the club in 2007 but never made a big impact and was flogged to Portsmouth for a fee in the region of £4 million in 2009.
Since then he has gone on to star in Serie A for AC Milan - earning a reputation as one of the best midfielders in the league and even Europe.
This summer he went to Schalke for €15 million as he wanted to return to Germany, to get away from racism controversies in Italy, and is having a great season in Gelsenkirchen.
Probably worth in excess of £15 million these days - Spurs would certainly have him back.
