Pirlo enjoyed a distinguised career, winning the Champions League twice and Serie A six times, as well as the World Cup in 2006 after he was named Man of the Match in the final.
"It's the chance to share a special evening doing what we love most. The game will be at San Siro, the venue for so many battles over the years, on May 21," the Italian maestro said.
Since retiring Pirlo has tried punditry, and says he would like to stay in the game somehow.
"I only ever played football, so I think I'll remain in this world. Becoming a coach is a hypothesis, but I don't know yet. I need to unwind for a while, then I'll have time to decide what I want to do," he concluded.
