The Italy playmaker, now 33, has claimed that he almost followed former AC Milan coach Carlo Ancelotti to Stamford Bridge before joining the Old Lady in 2011
The Juventus star will line up against the Blues on Tuesday evening, but admitted he was in deep negotiations with club officials, before AC Milan - his club at the time - pulled the plug on a deal.
The 33-year-old told the Daily Mail: "Actually, Milan wouldn’t let me go. I have a very strong connection with Ancelotti, so I was in touch with him when he went to Chelsea and I’m still in touch with him now he’s at Paris Saint-Germain.

"Certainly it would have been a different experience that I’d have liked, especially when I was 30 years old. So why not? But unfortunately it didn’t happen."
The midfielder has enjoyed somewhat of a renaissance since joining the Bianconeri, contributing to Juventus' unbeaten title success last season, before shining for Italy at Euro 2012.
Pirlo also admitted he is still looking to challenge himself, and refused to rule out a future move to the Premier League.
"Maybe, who knows? I don’t know what might happen. You never know. I still have two years left with Juventus, this season and next," he added.
"I like English football a lot. There are plenty of very good teams. They are very aggressive so it’s always entertaining to watch.
"It wouldn’t be a problem for me fitting into that particular style because I’ve played with different players with different characteristics throughout my career."
