One of the brightest young talents to have emerged from Australian football in recent years, Arzani became the youngest ever player to be named in a FIFA World Cup squad for the Australia national team when he travelled to Russia this summer.

Islamic Republic of Iran international Saman Ghoddos has signed a five-year contract with French side Amiens SC.

The Swedish-born Iranian began his professional career in Sweden's Division 1 Limhamn Bunkeflo in 2011 and Trelleborg in 2013 before progressing to the Superettan a year later with Syrianska.

The 26-year-old has spent his entire professional senior career with Al Ain, marking this as his first move out of the United Arab Emirates.

With Al Ain since 2008, the 2016 AFC Player of the Year has a cabinet filled with trophies playing for The Boss, which includes multiple individual honours, four UAE Pro League titles, a UAE League Cup in 2009, three UAE Super Cup and three UAE President's Cup.

Honda, who retired from international football after Japan's heartbreaking 2018 FIFA World Cup Russia exit in a last-gasp defeat to Belgium, put pen to paper for the 2018/19 season.

"It goes without saying that Keisuke has consistently proven himself at the highest level and we can't wait to see what he can do in Melbourne," said Victory head coach Kevin Muscat.

The talismanic 32-year-old, one of the highest profile names in Asian football, had been a free agent since departing Mexican club Pachuca.

"I am so happy to join the Melbourne Victory. I knew they were interested in me one week after the World Cup," he told Fox Sports.

"I really like a new challenge, that's me. I checked a couple of things. Melbourne Victory is the most successful club in the A-League. That's amazing. They became champs many times," he added.

Muto has signed an initial four-year contract at St. James’ Park after leaving Bundesliga side Mainz 05 – for whom he appeared against the Magpies in last summer’s friendly in Germany.

He becomes the fifth player to link up with Newcastle ahead of the new English Premier League campaign, following the permanent arrivals of Martin Dúbrvaka, Ki Sung-yueng and Fabian Schär, and the loan capture of Robert Kenedy.

Speaking about his move, Muto said: “I am very happy to be a player for Newcastle United. I am really looking forward to playing in front of the fans.

“As the first Japanese Newcastle United player, I am honoured to be a player for such a big club. I hope to achieve good results – that is what I am here to do. I would like to perform well and leave my name in Newcastle’s history.”

On his way to a second division German club, Lee said he's determined to prove he's made the right choice.

"I've always dreamt of playing overseas, and I felt I was at a point where I needed a challenge in my career," Lee said in a video message released by Jeonbuk. "I wanted to test myself against foreign players."

Lee said he made "an extremely difficult decision" to leave Jeonbuk and added he has nothing but fond memories from his time with the K League 1 club.

"I know I've chosen to go down a difficult path," Lee added. "I'll try to compete with the pride of a K League MVP and prove that I've made the right move."
