Real Madrid returned to Galacticos back in 2009 when Florentino Perez came back to power for the Royal club in Madrid. He brought in Alonso, Kaka, Benzema, Ronaldo. Apart from Kaka who was haunted by injuries the others turned out to be very good value for money. Xabi Alonso from the Basque Country has more recently turned out to be a very skilled coach as well.
So this it the jersey worn with slightly other squad numbers than what would be the case later. Ronaldo at 9, Benzema at 11, Kaka at 8, and Alonso at 22.
At the time La Liga was still the LFP and thus the sleeve badge reflects this.
And finally the name and number kit in detail:
The official Real Madrid name and number kit 2009/10 was from Sporting ID.
