The Spain worldwide was initially expected to move to China, but uncertainty surrounds his future, with Australia and Japan also mooted as possible destinations.
The 33-year-old also said he is trying to enjoy his last couple of games at his boyhood club and feels there is still a unique milestone for Barca to achieve before he leaves.
"I have a week-and-a-half left to enjoy and when the season ends my mind will be on the national team and my future".
Mikitani, however, is also the CEO of Barcelona's main sponsor Rakuten, further fuelling speculation that a deal was close after China's Chongqing Lifan denied they were in the hunt to sign Iniesta.
Hours after J-League side Vissel Kobe backed away from reports that a deal worth €25 million a season had been agreed with the Barcelona legend, Gallop made it clear the A-League means business.
Gallop confirmed there were A-League clubs interested in Iniesta, while accepting there would be plenty of competition for the star's signature.
The club added that although it would "deepen" its cooperation with Iniesta, "he will not join us as a player".
"I said that I would not go to Europe and apart from that all possibilities are open", Iniesta told beIN Sports after Barcelona thumped Villarreal 5-1.
"You will know when I tell you".
"It's true that I have various offers to think about and in the next week, 10 days, I'll try and decide which one is the best for me".
"To be honest, that amount of money doesn't seem realistic to me".
In the wake of that surprising news, the Spanish media now report that Iniesta will not play in China, but for Japanese club, Vissel Kobe.
