Even between the bitter enemies of Real Madrid Barça, there are many "famous families" who have played successively, such as the Portuguese king Figo, who is known as the "number one traitor in football", and the current Spanish national team coach Luis Enrique.
These stars, who are often reviled for betrayal, have to switch to the most unacceptable opponents for whatever reason, and in the face of the criticism of fans, they can generally only calm things with silence, except for one person.
That is the Cameroonian cheetah Eto'o who switched from Real Madrid to Barça, but sprayed Real Madrid's blood without reservation.
Others can only bow their eyebrows and obey when they become traitors, why is Eto'o alone in rebelling against the old master still full of firepower? It all started with Eto'o joining Real Madrid.
In 1997, at just 16 years old, the Cheetah had already shown extraordinary talent when he was spotted by a scouting agent named Jacob, who brought the African teenager to the Bernabeu after some manipulation. But as Real Madrid, which is star-studded in any era, there are very few opportunities and stages left for a young talent. In the three years since he joined Real Madrid, Eto'o has either played for the B team or on loan, and has only made three first-team appearances, which has made him increasingly resentful of Real Madrid.
It should be very normal for a young player under the age of 20 to not get a chance in the Real Madrid first team, but why can't Eto'o think so much?
There seem to be some other reasons besides football, such as skin color, at least Eto'o himself thinks so. Whether it is the club or the fans, local white players such as Raul and Redondo seem to be natural darlings at Real Madrid, while black players such as Eto'o and Markelele are always despised and excluded.
The disgruntled Cameroonians went straight to President Florentino to give advice, and the latter didn't even bother to heed his complaints, which further ignited the flames of cheetah's hatred. He was determined to leave the Santiago Bernabeu, the temple of countless dreams, and go to a place where he could use his talents.
As he matures, there is no shortage of homes, and Manzano, the Chinese Super League coach who later coached Guoan, Shenhua and other teams, led the Mallorca team that year.
Eto'o thrived on Manzano's defensive counter-attacking style, scoring 54 goals in three years to rank among La Liga's top strikers.
The Africans raised their eyebrows the most in the 2002/2003 Copa del Rey competition, where the semi-finals awaited them against Real Madrid, whom he hated most.
In the second leg of the Cup del Rey semifinals, Etoo scored twice to humiliate the old captain Hierro, and finally helped the team to reach the final and reach the top.
In the league, he faced Real Madrid in two games, three shots and two passes, the director slaughtered 5:1, and gave his old club two humiliating defeats, "Real Mark" will forever remain in history, so that the reviled Real Madrid fans also have to applaud him.
At this point, Eto'o will also turn, his face will be beaten, the Bernabeu has also applauded, and it is said that the grudge with Real Madrid should end here, but if it is only like this, it is too underestimating the energy of the cheetah.
Eto'o caught the attention of Barça due to his excellent performances at Mallorca, which are friendlier to black players than Real Madrid. So in the summer of 2004, Eto'o switched to former arch-rivals to join Barca.
In his first season at Camp Nou, the Cheetahs scored 24 league goals to help the Reds and Blues regain the La Liga title for the first time in six years.
For the Barça people, who have historically been suppressed by Madrid in all aspects, from political economy to football, the victory over Real Madrid is their most raised moment.
Perhaps influenced and inspired by the collective, Eto'o was embarrassed at the championship ceremony, holding a microphone and leading Camp Nou to repeatedly shout "Madrid, bastard, come to the championship", venting his anger can be described as a great revenge.
Although his public abusive remarks earned a fine of 12,000 euros imposed by the Spanish Football Association, it is conceivable that it is the happiest money cheetah has ever spent.
