Arsenal interim manager, Freddie Ljunberg, cannot take charge of the club beyond February, the UK Mirror reports.
Ljunberg stepped into the role on Friday, after Unai Emery was sacked by the club.
However, the Swede also holds a UEFA A Licence and does not have a UEFA Pro Licence.
This implies he can only manage in the Premier League and European competitions for 12 weeks.
Ljungberg has done his coaching courses at the Football Association of Wales’s (FAW) highly respected programme, which has also been attended by the likes of Thierry Henry and Mikel Arteta.
But after his appointment on an interim basis, the Gunners could seek some form of special dispensation, if he impresses while in charge.
