Racing Club Lens have backed FIFA's decision to punish Chelsea for luring teenager Gael Kakuta away from the French club.
The Blues face not being allowed to sign any new players until January 2011 for their previous conduct, having taken Kakuta to Stamford Bridge in the summer of 2007.
Chelsea and the player have also been fined 780,000 euros, while also being forced to pay Lens training compensation of 130,000 euros.
Lens chairman, Gervais Martel, told AFP: "We expected this kind of decision. The player was under contract with us and they came and stole him away from us.
"Chelsea didn't follow the rules. They contacted the player when he wasn't even 16 yet and while he had been contracted to our training group from the age of eight.
"The financial sanction isn't over the top given the nature of the infringement, but it's really quite significant when it comes to not being able to recruit players.
"It's an important message given that protecting up and coming youth players who are contracted to clubs is an issue being followed closely by (UEFA president) Michel Platini."
