Indonesian champions Persipura Jayapura have made a successful appeal to the Court of Arbitration for Sport (CAS) regarding their potential involvement in the 2012 Asian champions League.
The Indonesian Super League outfit were not included in the draw for the Asian club tournament as the Indonesian Football Association (PSSI) does not recognise the breakaway competition they are now playing in.
PSSI did not enter Persipura in the ACL draw so the club took their case to the CAS who have acknowledged their right to play in the 2012 competition.
"Adelaide United FC have made extensive legal submissions to the Court of Arbitration for Sport (CAS) which it believes will ultimately result in the appeal being refused," read a club statement.
"Until Adelaide United FC is permitted by CAS to make full submissions on the issue of jurisdiction and on the merits, which arguments are being fully supported by AFC and now the PSSI, the status of the AFC Champions League games remains unclear.
"The worst case scenario for the Club is that it may be obliged to play Persipura in a knock out game for the final AFC Champions League position. The Club will cross that bridge when and if it has to. In the interim it is proceeding on the basis that its position in the 2012 AFC Champions League competition remains in place."Persipura were due to play Adelaide United in the play-offs with the Australian club also complying with the CAS.
The PSSI, Asian Football Confederation (AFC) and Adelaide United have to submit evidence by February 6 with a final decision to be made by February 10.
