Sydney FC Chief Executive Officer Tony Pignata will fly to Italy over the weekend to conclude the signing of the contract in what is the biggest signing in Australian sports history.

“This is huge for Sydney FC, huge for the A-League and huge for Australian football,” said chairman Scott Barlow.

“We feel honoured that Alessandro has decided to play for Sydney FC and we share his excitement that a move to Sydney FC will create a lasting legacy for football in this country.

“I want to thank Tony Pignata and Lou Sticca for the outstanding work over the last few days in progressing discussions with Alessandro and look forward to Tony finalising the contract in Italy over the coming days.”

However later on Friday evening, Sydney move to clarify the deal wasn't complete, with Barlow stating they'd agreed to enter into final discussions but not signed off on the move yet.

“Alessandro Del Piero has not signed a contract with Sydney FC as yet. The two parties have agreed to have a meeting in Turin early next week to confirm the possibility of signing a contract,” Barlow said. 

Del Piero had been linked with teams in the USA, China and the Middle East since finishing his career with Juventus in May.

Sydney will open their A-League season away to Wellington Phoenix on October 6.
