Atletico Madrid will begin legal proceedings on Monday regarding the transfer ban handed out by FIFA last year, ​AS report.

Atletico will be represented at the Court of Arbitration Sport headquarters in Lausanne, Switzerland by Munich law firm Marten's employee Christian Keidel and will argue the punishment originally handed out was unfair.

The punishment prevents Atletico from signing players until January 2018, having been found guilty of breaking rules regarding the signings of minors, and they were also fined £620,000. They are confident of a positive result and that they will be able to sign players in the summer.

FIFA originally investigated 183 cases of Atletico signing minors, while Real Madrid were also under the spotlight for a similar breach having been involved with 39 minors. The CAS appeal procedure states that the panel of experts shall consist of three arbitrators and that each party will elect one. 

The chairman of the Arbitration Division will select the third party but if the parties reach an agreement or if the Court of Arbitration believes it appropriate then just one arbitrator will be appointed.

Atletico will be eager to see the transfer ban overturned, especially given their recent prowess in the market. The La Liga giants have become well known for their exceptional recruiting powers, consistently producing quality teams after selling top players, and they will need the ability to sign more players should any of their first-team stars leave in the summer.

Striker Antoine Griezmann has been heavily linked with a move away from Atletico throughout the season, with Manchester United believed to be interested, but Diego Simeone's side will need to replace the Frenchman in the transfer market if they want to stay competitive after his sale.
