Chelsea have found themselves in trouble a few times in the past few decades for their transfer activity.

The west London club were heavily criticised for their pursuit of Ashley Cole in the mid 2000's, when in 2005 the then Arsenal player met Jose Mourinho, Peter Kenyon and agent Jonathan Barnett in a hotel to discuss a possible move.

Chelsea, Cole, Mourinho and Barnett were all given hefty fines, but to the sheer dismay of Arsenal fans, the Englishman would complete his move across London a year later.

And the Blues found themselves in trouble again a few years on from that saga. Although Gael Kakuta made the move from Lens to Chelsea in 2007, the French outfit reported Chelsea to FIFA two years later and the English club were banned from signing players for two transfer windows.

Fortunately for Chelsea, their appeal was successful and they were later cleared of any wrongdoing by the Court of Arbitration for Sport in February 2010, meaning they did not have to serve the ban after all.

But, after going through so much trouble to sign Kakuta, what exactly happened to him?

KAKUTA HAS NOT FLOURISHED AS EXPECTED

A lot was thought of the former Lens player upon his arrival to west London, with Carlo Ancelotti claiming in 2009: "He is a player who can be part of this club’s culture. At his age I have never seen a player with his talent."

However, like so many talented youngsters, Kakuta's career did not flourish as expected.

Although he featured sporadically in the first team during his first few years at the club, he was eventually shipped off on loan for first team football elsewhere.

During his spell at Chelsea he would spend time on loan at six different clubs, including Fulham, Bolton and Lazio; to varying degrees of success.

But, after failing to breakthrough at Chelsea, his eight year spell at the club finally came to an end in 2015 when he signed for Spanish club Sevilla.

But it only went downhill from there.

After failing to make the grade in Spain, where he fell out with boss Unai Emery and made just two league appearances, the French born player then made the move to China, and is now back in Ligue 1 with Amiens SC.

That means, despite being 26-years-old, Kakuta has already played for 11 professional clubs: eight of those being whilst on loan.

It's fair to say Kakuta's career has not panned out as expected.

KAKUTA REVEALS WHY HE DIDN'T MAKE IT AT CHELSEA

The former wonder-kid has since expressed his regret at not making to most of his opportunity at Chelsea, and revealed that his mentality as a youngster was the major reason why he failed to make the grade in England.

Speaking to Foot Mercato last year, per FourFourTwo, Kakuta said: "When you have a high salary it's difficult to find a club that will agree to take part of that on. Those who you can reach agreement with are not necessarily clubs where you want to go."

"During my loans, I had my share of responsibility and I didn't really work. I don’t have the mentality I do today."
