An Al Jazira official confirmed that the Abu Dhabi-based club are in talks with Hosogai, who has been capped 25 times by Japan and is seen as the perfect replacement for Jucilei.
Hosogai started his career with the Urawa Red Diamonds before going on to play for Bayer Leverkusen and Augsburg. He joined Hertha Berlin in 2013 and has represented the Bundesliga outfit 53 times.
"We are in talks with the player (Hosogai) and he seems to be happy with our offer," the official told The National. "So we are hopeful of a deal but nothing is finalised."
The official added: "It is the time of the year when everyone is looking forward to transfer news but we can’t reveal each and everything on the negotiations or signing new players until they are confirmed, signed on paper.
"To reveal our talks with prospective players could have damaging results and breakdowns on the negotiations we are on.
"Hence the club management has decided only to announce the new players officially once the deals are completed and signed."
