Now being represented by Just Football, Iheanacho pulled out of a contract with First Eleven and Henry Galeano two years ago.
The deal is said to be worth around £25million with a buy-back clause chucked in to semi-ring-fence (Man) City's investment.
The UK Sun have however published photos which proved that Iheanacho indeed met and spent lots of time with Galeano.
Galenao himself has apparently also submitted an affidavit claiming he spent "hundreds of hours" with Iheanacho.
If found to be lying to the court, Iheanacho could be charged with unsworn falsification which is a jail able offence under Pennsylvania Law.
His company First Eleven Management has alerted Leicester City of its claim to Iheanacho's image rights.
Iheanacho featured 28 times for City last season, scoring seven goals.
Leicester City boss Craig Shakespeare had admitted he was hopeful of a deal to bring Iheanacho to the club last weekend.
First Eleven Management claim they now own his rights under the company name "Team Kelechi LLC" and have alerted Leicester City.
