I believe the first objective for City is to have the allegations thrown out and any threat of sanctions removed.
Talk of then attacking FFP and UEFA may be misplaced. Khaldoon has said that City know who is behind the moves to undermine and discredit the Club. Attention could focus on individuals (in the way Platini was forced out) and organisations behind besmirching City. They could be pursued and claims made for damages. It is an alternative view that does not attack UEFA as such but those behind the sustained campaign aganst Manchester City, CFG and our owners.
