El Clasico: Who are the greatest Africans to play for Real Madrid or Barcelona?

Song transferred, at the height of his powers, to Catalonia to join Barcelona from Arsenal.

The box-to-box midfielder was indispensable for Arsene Wenger's Gunners, but it never quite worked out for Song in La Liga, and he subsequently returned to England on loan at West Ham United.

He's currently playing in Djibouti following spells with Sion and Rubin Kazan, and it's safe to say that his career hasn't lived up to the early promise of his pre-Barca years.

During his playing career, the former Tanzania coach was a glittering wideman who enjoyed dismal fortune at Barcelona, where injuries completely shattered his career in Catalonia.

The 1994 African Footballer of the Year scored twice in the Nations Cup final that year as Nigeria defeated Zambia, and also clinched honours in Portugal, Egypt and in his homeland.

Yet despite a clutch of honours won with Barca, it’s tempting to beg the question, what might Amuneke have become had injuries not taken their toll?

Adebayor has been a fan favourite at almost every club he has played at, but he is also known for his controversial nature and at times it has overshadowed his excellence at some European giants.

He made 143 appearances for Arsenal managing 62 goals, of which 30 came in the 2007/08 season, which remains his finest campaign.

His brilliance flickered at Manchester City and Tottenham Hotspur, but he never truly looked the part during a brief loan spell with Real in 2011.

He's currently a free agent after leaving Paraguayan giants Olimpia.

Diarra doesn’t always get the credit he deserves for the consistent excellence he brought to the table at Real Madrid during his time at the Bernabeu.

Between 2002 and 2008 the Mali international won six consecutive league titles with Olympique Lyonnais and then Real, helping the Spanish giants to end a four-year trophy drought with their championship triumph in 2006.

Finally, largely thanks to Diarra’s positioning, awareness and sharp tackling, Los Merengues had a long overdue replacement for Claude Makelele.

Geremi won two Premier League winner's medals under Jose Mourinho at Chelsea, to add to his significant honours haul won with Real Madrid.

A hardworking-if modest-operator, the former Newcastle United midfielder was never a genuine Galactico at Real, but his attitude and leadership skills still set him apart, notably during two Champions League triumphs.

Keita is one of the most decorated African players in history, and he certainly achieved great success in Spain.

He left Barcelona after four years, having won 14 trophies under Pep Guardiola and the Malian midfielder has been praised to the hilt by his former boss, who has long viewed the West African as a key component of his magnificent side.

He last played for El Jaish of Qatar, leaving the club in 2017.

The latest African superstar to taste life with one of the two Spanish giants, Aubameyang finally ended his Arsenal purgatory by signing for Barcelona during the winter window.

After losing his way in North London, he's hit the ground running in Catalonia, and became the third all-time top scorer in the Europa League when he netted against Galatasaray earlier this week.

Heading into his first Clasico, he's scored five in his first six Liga appearances.

A legend at Chelsea, where he managed 17 goals in 168 appearances and won a host of silverware, Essien moved to Real on loan for a season in 2012.

By then, injuries had taken their toll on the Bison, although his class still convinced 'Daddy' Jose Mourinho that he could be an asset at the Bernabeu.

Now 39, Essien is currently part of the coaching staff at Danish side FC Norsjaelland.

Toure was an integral part of a Barcelona squad that had begun to revolutionised how football was played throughout the world, winning the Champions League before leaving his teammates to enjoy greater success without him.

The Ivorian was seen as a more defensive player by Pep Guardiola than he became Manchester City, and played in the holding role or in the defence, which was where he won the UCL in 2009.

The four-time African Player of the Year was among the key inspirations behind City's rise to dominance, although he left the club under something of a cloud.

Not only is Eto’o one of Africa's finest frontmen, but one of the world's greatest strikers of all time.

The Indomitable Lion led the line for five years at Barcelona, where he has an impressive collection of titles. In 232 games played for the Catalan giants, he won two Champions League titles, three La Ligas, one Copa del Rey and four other Spanish Cups.

He also made decisive contributions at vital moments, and stands alone as the greatest African player to feature for either Barca or Real Madrid (whom he also represented briefly at the beginning of his career).
