The A-League new boys have previously been linked with the 17 cap Italian but last night posted a tweet showing a picture of a diamond, sparking speculation the deal has been done.

However FTBL understands the star will be unveiled at special ceremony in Melbourne's Western Suburbs on Thursday morning.

The signing comes after Melbourne Victory were blocked from signing Diamanti as a special guest marquee three years ago because the FFA believed he was not famous enough to bring in new fans to the A-League.

The 36 year old attacking playmaker has remained on the radar of A-League since though - and will now be a pivotal part of Western United's attacking line up, playing just behind former Socceroo Scott McDonald and linking up with Greek midfield marquee Panagiotis Kone.

Diamanti first made a name for himself as a 16 year old with Prato, notching up 18 goals in 59 games in the Italian lower leagues as a teenager.

A series of loan spells eventually saw him move to Serie A with Livorno in 2007 where he repeated his good run of stats, scoring 17 times in another 59 games.

West Ham brought him to the EPL and made an instant impact on his debut where he scored from the spot against Liverpool – despite tripping over as he struck the ball.

A spot kick expert - he scored from the spot five times for West Ham with another three from open play - he was a fan favourite at the Hammers but returned to Serie A with Brescia after just one season.

The move ended in a transfer row over the fee and a season later, Diamanti moved again to Bologna on a co-ownership deal.

There he enjoyed his most successful period including scoring this outstanding freekick against Cagliari to keep Bologna out the relegation zone.

The biggest transfer fee of his career saw him make a €6.9 million move to Chinese Super League side Guangzhou Evergrande in 2014 which turned into a series of loans to Fiorentina, Watford and Atalanta until he left China as a free agent.

When the move to the A-League was blocked by the FFA in 2016, he flitted between Palermo, Perugia and Livorno until Western United finally sealed a deal to bring him to Australia.

With tattoos to match his talent, the colourful playmaker is now set to bring life to Western United's attack and strike fear into keepers and defenders from set pieces.
