Alen Halilovic agreed to a deal to join Barcelona from Dinamo Zagreb in March and his attorney says it will be upheld despite a FIFA ruling against the club.

FIFA sanctioned Barcelona due to their apparent illegal transferring of players under 18.

"I cannot foresee for one second that my client, Alen Halilovic, will not be able to play for Barca," lawyer Jean-Louis Dupont told Spanish radio station RAC1 on Thursday.

"This is an operation that has been completed prior to the sanction."
