The 36-year-old midfielder is set to join former England international Frank Lampard and Spain's all-time record goalscorer, David Villa, at Yankee Stadium
Juventus playmaker Andrea Pirlo will seal a switch to New York City FC on Friday,
The Italy international still has a year to run on his contract with the Bianconeri and had previously claimed that he would only consider leaving Turin if Massimiliano Allegri's men lifted the Champions League earlier this month.
However, despite Juve's 2-1 loss to Barcelona in Berlin, the uncertainty surrounding the midfielder's future has only intensified in recent weeks and, on Saturday, the 36-year-old attended a New York Yankees baseball game at Yankee Stadium - which is also home to NYCFC.
Pirlo will join former England international Frank Lampard and Spain's all-time record goalscorer, David Villa, at a franchise that only entered the league this season.
Set-piece specialist Pirlo also played 115 matches for Italy and was a key component in the side that tasted World Cup glory in 2006.
