Having seen the amount of money that the Saudi league is throwing about, his contract could well be for a couple of phone calls a year.Mancini's City contract was heavily incentivised on top of his basic. So in his first full season (2010/11) we won the FA Cup and finished in the top four. I think that netted him about £5m in total.
Winning the league increased that and he renegotiated his City contract, to the point where he worked be earning something like £11-12m in that 2012-13 season.
Also, he didn't personally have to provide that consultancy to Al Jazira, his company did. So he could legitimately get someone else to do it.
The people involved have probably paid more for someone to DJ at a family birthday party.
