Chelsea received a two transfer window ban by FIFA stating, Chelsea cannot register any new players until January 2011. Chelsea has responded that they will appeal with the utmost strength possible. This ban of about a year and a half was given to Chelsea because of the way they dealt with signing Kakuta. Apparently Chelsea persuaded the player to break his contract with his previous club, Lens, and to join Chelsea.
What could also surprise many is that Manchester United could have a similar ban on their hands, as club Le Havre stated, they are pursuing a "very similar" case as the Chelsea Lens case. It seems that Manchester United "stole" young prodigy Pogba by telling him not to sign a professional contract with Le Havre, but to come to Manchester and sign one with the English giants.
