Steven Gerrard's cousin Anthony Gerrard earned a rare moment of fame on Sunday - sadly, it was for all the wrong reasons. The Cardiff City sub came on in extra time and missed the critical penalty which saw the Bluebirds lose the Carling Cup final to Liverpool.
And in a week when Novak Djokovic's younger brother has been grumbling about how his famous name makes it harder for him, it struck us that it can't be easy toiling away in the shadow of a legend.
So to make both Anthony and Marko feel less alone, we decided to take a look at some of the other journeymen who are overshadowed by superstars in their family. Here's our top 10:

Carol Lewis, Carl's younger sister
Winning a bronze medal in the long jump at the World Championships and holding the US record for two years might not seem a bad return for a career in athletics. But when your older brother - whose name is just one letter different to yours - has nine Olympic gold medals sitting on the mantelpiece and is lauded as one of the greatest athletes of the late 20th century, we'd bet it just doesn't feel quite as good.
Eddy Baggio, Roberto's younger brother
The Italian footballer started his career alongside his famous brother in Fiorentina's youth system. But while Roberto went on to a life of international glory at the top of the game, Eddy never made it onto the pitch in a Serie A match and ended up languishing in the lower leagues. He played 86 matches in Serie B for a string of different clubs including Catania, Vicenza and Pisa before retiring three years ago.
Mark Wilkinson, older brother of Jonny
'Sparks' Wilkinson started out as a coach, but went on to play alongside his brother Jonny at the Newcastle Falcons. After three mediocre seasons he returned to the dugout to become the Falcons conditioning coach, and is now involved in the nascent Wilkinson sporting clothing empire.
Rudy Clay aka Rahman Ali , brother of Cassius/Muhammad
It's a tough gig being the younger brother of one of sport's genuinely legendary figures. He failed to win selection for the Olympics while an amateur, then had an undistinguished professional career with 14 wins, three losses and a draw. He was knocked out in his final fight by Jack O'Halloran, a boxer who went on to become the actor who played Non (the big, dumb Kryptonian super-villain) in the first two Superman films.
Enoch Balotelli, brother of Mario
The Italian striker's 19-year-old brother is desperately trying. His name alone has opened a few doors - but he has so far struggled to get through those doors. He had a trial for Stoke and ended up playing for the Potters on one occasion, but they did not offer him a deal - nor did Sunderland, who took him on trial last month.
John Terry's brother Paul Terry
The former England captain's older brother has spent several years playing in the lower leagues in England, counting Dagenham & Redbridge, Yeovil Town and Leyton Orient among his clubs. The only time he ever displaced his famous sibling in the newspapers was when he had an affair with a team-mate's fiance. The player, Dale Roberts, committed suicide after finding out about the affair.
Carlos, and Nigel and Jordan Ridd-Hasselbaink, brother and nephews respectively of Jimmy Floyd Hasselbaink
Massively overshadowed by his famous younger brother, Carlos (pictured below) muddled along for years in Dutch football struggling to earn pitch time: he played just 92 times in eight seasons at Haarlem, for example, before hanging up his boots in 2005.
Jimmy Floyd's nephew Nigel is currently doing well with St Mirren in the SPL, while Jordan is plying his trade with, er, Bognor Regis Town FC. And no, we didn't just make that up.
Rhodri Giggs, brother of Ryan Giggs
The Manchester United legend's brother Rhodri had a chequered life: after starting out with Torquay, his career hit the skids and he ended up in prison after getting into a fight with a pair of Manchester City fans outside a nightclub. Rhodri then spent several years as a delivery driver, but is currently player-manager of Salford City. Ryan has had by far the better career, no doubt thanks to his habit of scoring more often.
Patrick McEnroe, younger brother of John
Reaching the world's top 30, winning an ATP Tour singles title as well as the French Open doubles, and becoming a successful Davis Cup captain would be a dream come true for most of the thousands of people who dream of playing tennis for a living. But when you're the brother of a seven-time Grand Slam champion who became one of the most famous sportsmen on the planet during the 1980s, it just doesn't quite cut it.
Ralf Schumacher, Michael's younger brother
People criticise Bruno Senna for trading on his name to earn a place in Formula One, but it's nothing new. The little brother of the seven-times world champion made his way into motorsport's premier series and managed to hang around for 11 seasons despite year after year of underwhelming performances. He had a few brief moments of glory - chiefly with a hat-trick of wins in 2001 and two more in 2003 - but ultimately six wins from 180 races was a very poor record for a driver who was one of the highest-paid stars in the sport, and who often had very good cars at his disposal.
