Manchester City are holding their breath as they wait to discover what the CAS has uncovered regarding their youth team signings.
The implications of the CAS findings could be a transfer ban, or a hefty fine for the club. City are hoping it will be the latter, or no punishment at all.
The CAS are looking at a case involving the transfer of Benjamin Garre from Velez Sarsfield in Argentina, when the player was only 15.
The club in Argentina claim City had dealings with the player when he was just 15, even though the paperwork to sign him was completed right after his 16th birthday.
It is unclear how CAS will rule, but the implications could be very serious for manager Pep Guardiola's transfer plans in the coming windows.
