Did Barcelona tiki taka reach the stage of aging?

Barca defeat in front of the Royal showed many flaws in the team coached by Luis Enrique and alarming statistic.

Barcelona received a severe defeat at the Santiago Bernabeu Stadium against Real Madrid 3-1, Lionel Messi colleagues appeared poorly and worrying defensive gaps... these things given way of thinking and doing technical and statistical analyzes.

There were statistically somewhat disturbing in terms of average age of the players... that age where the rate of 28.7 of the 11 players who relied on them for Luis Enrique estimated while Real Madrid (26.6).

This statistic looks impressive dramatically when we see that six players from the 11 who started the game in the Catalans exceed the age of 30: Bravo (31 years), Alves (31), Mascherano (30), Matthew (31), Xavi (34) and Iniesta (30).

While Real Madrid, there two of the 11 who exceed the age of 30 and two Iker Casillas (33) and Pepe (31).

In the same vein Real Madrid came to this game with four players under the age of 25: Carvajal (22), Isco (22), James Rodríguez (23) and Cross (24)... while Barcelona only came with only one player under the age of 21, a Neymar (22 years).

The most affected lines of the age difference is the defense and the center line... with the rate of 3.5 (the defensive line) and 5.5 (in the midfield) more than Real Madrid in terms of past rate, the back line of the Barcelona rate was 29.75: Alves (31), Pique (27), Mascherano (30) and Matthew (31).

While Real Madrid was his defense line rate of only 26.75 with Carvajal (22), Pepe (31), Ramos (28) and Marcelo (26)... in the midfield of the Catalan team arrived about 30 rate: Xavi (34), Iniesta (30) and Busquets (26)... while the rate of central line Real Madrid barely reached 24.5: Rodriguez (23), Modric (29) Cross (24) and Isco (22).

Several questions and doubts Barcelona left after El Clasico especially from midfield defensive line hand, players like Pique and Alves addition to Xavi did not return at the same level compared to the past seasons, has already Barcelona become "old team"?
