In March 1975, West Germany – the newly crowned world champions – came to London’s Wembley Stadium for a friendly against England.

Among the German squad was a 28-year-old striker who’d already attracted a lot of attention from the British media: not because he’d been hailed as the new Gerd Müller, Germany’s legendary goal scorer, but because of the colour of his skin.

Erwin Kostedde was the son of a white German mother and a black US soldier, and he had been on the receiving end of racism for most of his life – even during what he considered to be the best years of his career, at Kickers Offenbach.

He talks to Kristine Pommert about how racist taunts from supporters and even fellow players affected his game – and how he feels about being a trailblazer for young black players today.

In 2014, fighter Cecilia Braekhus helped end Norway’s 33 year ban on professional boxing, thanks to a parliamentary points decision.

The so-called ‘knockout’ law had been in place since 1981 because the Norwegian parliament thought professional fights - lasting up to 12 rounds and with no helmets - were too dangerous.

It meant that Cecilia and other Norwegian boxers had never been able to fight professionally in their home country. They also had to train abroad.

Despite the ban, in September 2014, Cecilia became the first undisputed world champion in women’s boxing after unifying the welterweight titles.

She then turned her attention to securing another victory, and three months later, the Norwegian parliament voted 54 to 48 to lift the ban on boxing.

Cecilia Braekhus spoke to Jane Wilkinson about being able to fight professionally in Norway for the first time.

In 2004, the Caribbean island of Puerto Rico went into their opening basketball game of the Athens Olympics as massive underdogs against the USA.

The Puerto Rican side had lost five consecutive games by double digit points to the USA's star-studded squad in qualifiers and warm ups.

But the unfancied team defied the odds with the performance of a lifetime, led by their own inspirational star, Carlos Arroyo. Robert Nicholson hears his story in this Whistledown production.

In 1992 history was made at the Olympics in Barcelona as 12 former Soviet republics competed for the first and only time as the Unified Team.

It was the final time the countries who had been part of the USSR took part in sporting events as the same team. And it marked a revolution for athletes who had been part of the Soviet athletics machine like World Champion Ukrainian fencer Sergei Golubitsky.

He speaks to Ashley Byrne about the mixed feelings he and other athletes had as their countries turned their back on communism and gradually embraced a new way of doing elite sport. A Made in Manchester production.

Rafael Nadal and Roger Federer were the undisputed King of Clay and King of Grass respectively. But who would win on a hybrid court made up of half grass and half clay?

That was the idea from Argentinean creative entrepreneur and tennis fan Pablo del Campo, who wanted to stage the exhibition match which would be watched by millions.

As Rafael Nadal retires from professional tennis, Pablo tells Uma Doraiswamy how he made the iconic court possible in May 2007 in a bid to find out who would win the Battle of the Surfaces.

In November 1973, Netherlands women’s football team lined up for their country’s first official international. It was a major step on the road to the development of the game, both in the Netherlands and in England, who were their opponents that day.

Now over 50 years on from that game, with the two countries both now powerhouses in women’s football, Matthew Kenyon speaks to one of the players from the Dutch team who was just 16 years old at the time, Ellen Popeyus, for whom the game was another chance to prove the doubters wrong.

In 2008, Union Berlin played in the third division in German football. They were best known for the extraordinary atmosphere at their unique stadium, the Stadion An der Alten Försterei, which is surrounded by forest in East Berlin.

But long term financial challenges for the club meant the stadium was becoming too run down to use. The team was at risk of having to move, until fans volunteered in their thousands to take on the renovation work themselves.

Lifelong Union fan Sylvia Weisheit oversaw the project, and she tells her story to Kit Holden. This is a Whistledown production for the BBC World Service.

The Euro 2016 qualifier between Serbia and Albania in October 2014 was politically charged between the two nations. But the opening exchanges in Belgrade had passed without major incident, until a drone carrying a flag appeared in the sky above the pitch, with violent breaking out on and off the pitch.

Albania’s captain Lorik Cana and football reporter Nick Ames speak to Jack Butcher about that infamous night in the Serbian capital.
