It follows news that Mohammadi's former Launceston United teammate Fletcher Fulton had also stepped up to the state league with Riverside Olympic and while their former club begins unveiling its Northern Championship squad.

City's new NPL coach Roger Hardwicke said Mohammadi, who hit 18 goals in 20 matches to finish third in the race for last season's Northern Championship golden boot, had "fitted seamlessly" into the NPL squad.

"Yasin provides us with another attacking option to worry defences this season, his skill and technique make him a handful for any defence," Hardwicke said on City's Facebook page.

"We need to have more than one threat upfront and we are starting to have that now with our attacking options all capable of creating and scoring goals. It's been really encouraging to see them all work together at training and start to get an understanding."

The signing will provide a different dimension to the frontline at Prospect which has been heavily reliant on state representative Noah Mies and Australian futsal star Jarrod Linger.

Mohammadi, who scored in each of his last five appearances for United, has also represented Tasmania at the highest level on the futsal court alongside Linger.

"I'm really excited about joining Launceston City and hope to develop my game to a higher level and contribute to the success for the club." he said.

United were quick to wish their former favourite well at statewide level with club stalwart Ian Calcraft saying on City's post: "Congrats Yassie. We are proud of what you did at United and I wish you well in state league."

The Birch Avenue outfit swiftly filled the void, announcing several squad players as it seeks to build on last season's third-place finish behind champions Northern Rangers and runners-up Devonport.

Reigning best and fairest winner Will Rodman has re-signed. The box-to-box midfielder, who previously played NPL at Launceston City and won the 2018 Northern Championship with Riverside, was a key signing in Glenn Reading's first year in charge of the senior side.

Fit-again attacker Aidan Rigby, who was league golden boot winner in 2017 with 22 goals having previously played NPL with Northern Rangers, has also rejoined along with key defenders Ryan Radcliffe and Josh Freestone, who signed from Launceston City last season.

Meanwhile at Windsor Park, Riverside Olympic announced Jo Haezebrook as their Northern Championship men's head coach.

Recently moving from Sydney, the Belgian has more than 30 years playing and coaching experience.

Director of football Alex Gaetani said: "Jo's approach to football and his playing principles align with what we are building towards. He will be an asset to our Northern Championship team and will help improve our young playing group."

The Northern Championship kicks off on March 23 with United hosting Riverside, Rangers beginning their title defence at Burnie, City welcoming Ulverstone to Prospect and Devonport playing Somerset.
