Chelsea's policy of signing every young player in the world has divided opinion for years. The Blues sign "Next Big Thing" after "Next Big Thing", but players rarely have an impact on the team.
For a club with a successful academy, their ability to churn out something disappointing never ceases to amaze.
Here are seven former stars who failed to vote at Stamford Bridge.
In 2007, there were few exciting young players like Gael Kakuta. The French was an infallible success, and the countless prizes of the Ballon de Or were almost certain to follow. The Chelsea was struck by a heavy fine and the prohibition of transfer for their pursuit of Kakuta, such was the excitement that surrounded him. If only things worked even close to that.
He made his debut in 2009, and the sky was the limit for Kakuta. However, Chelsea struggled to find a place for him in the first team, and was instead lent to players of the caliber of Fulham and Bolton Wanderers, as well as an apparently mandatory spell with Vitesse, but he failed to amaze with any of them .
It was released in the summer of 2015 and, after a period in China, it turns out to be Rayo Vallecano.
Now 27, it seems unlikely that we will see Kakuta lift the Gold Ball any time soon.
Josh McEachran should have led the England in more world cups, just ask any Chelsea fan. The midfielder was one of the most acclaimed products of the club's academy in history, and they fought against Real Madrid's interest in maintaining it.
He also tried to make him a star of the first team, but Andre Villas Boas had other ideas when he joined the club in 2011. He froze the midfielder before McEachran was forced to go out on five clubs. It ended up being sold for a sum of six figures in 2015.
The 26-year-old now plays his soccer for Brentford, and while that is a step back from Chelsea, you can bet he is happy to finally be able to spend more than one season at a club.
The story of Bertrand Traore is still a bitter pill to swallow for Chelsea fans. When he officially joined the club in 2014, he was one of the club's most exciting prospects. At the beginning of 2016, Traore scored four goals in five games and seemed to be a star of the future.
However, many believed they were not the finished product, and was loaned to Ajax for the 2016/17 season. He endured a mixed season, but helped the Eredivisie team to the Europa League final, before securing a € 10 million transfer to Lyon in 2017.
The 23 year old has enjoyed several impressive seasons in France, leaving many fans dreaming of what could have been. Did it underperform or simply didn't give you enough chances to test yourself?
One of the most prolific strikers in the history of youth football, Dominic Solanke has done everything possible to earn a place in Chelsea's first team. He scored goals without losing time, but it was still not enough for him at Stamford Bridge.
He only made an appearance for Chelsea, coming in the 2014/15 Champions League, before closing his contract and securing a trip to Liverpool.
However, after drawing only once in 27 appearances, Jurgen Klopp sold Solanke to Bournemouth for 19 million pounds in January. He made his debut for the Cherries a few weeks later, but is still looking for his first goal.
Brazil has produced some great players in history. Pele, Ronaldinho and Kaka contributed to their success story, but Lucas Piazon was better than everyone … or at least it had to be. The Blues won the tender for its signing in 2011, and the fans were in tears of joy at what the future might hold.
He made his debut in 2012, but was given only three games to show off his skills, before Chelsea decided to add him to the loan army, which usually marks the end of their time at the club.
Believe it or not, Piazon is still a Chelsea player. The 25-year-old has joined Chievo Verona on loan in January, but his days as part of Chelsea's set-up are certainly running out.
20 – Slobodan Rajkovic

Imagine a combination of John Terry and Nemanja Vidic. That was a sixteen year old Slobodan Rajkovic, and Chelsea did not hesitate to shell out 2 million euros to sign the young man in 2005. This little boy could play, and he was destined to the maximum.
He spent a lot of time on loan in Eredivisie because Chelsea simply couldn't get a work permit for the Serbian. They tried for six years, but eventually gave up on him in 2011, selling him to Hamburger SV for the same amount they paid for him in the first place.
Rajkovic currently appears for the Palermo in Serie B, and certainly fell out of the spotlight. People have even stopped updating their Wikipedia page, and the world seems to have forgotten the unfortunate Serb.
Having established himself as one of the brightest prospects of England on loan with Watford in the 2012/13 season, the future looked bright for Nathaniel Chalobah. So Chelsea rewarded him in the only way they knew – sending him a handful of useless loans.
He found the hard-to-find minutes almost everywhere he went, including a frankly grotesque spell with Napoli. After five wasted years, Chalobah's career went to the starting point when he obtained a definitive transfer to Watford.
Somehow at only 24, Chalobah is still in the Vicarage Road books, where injuries derailed his career. He has only made 21 appearances in two years, but he still has plenty of time to come well.
