Piet De Visser has stated that a move for the Argentine maestro has been on the agenda over the years.
The West London club are backed by Russian billionaire Roman Abramovich, who has supported the Stamford Bridge club with his investment over the last decade.
With many dreaming of Messi potentially leaving boyhood club Barcelona and moving to the Premier League, Blues scout Piet De Visser has revealed that a move for the Argentine has been discussed in the past.
The 80-year-old Dutchman is widely acknowledged as playing a significant role in bringing players such as Ronaldo and Romario to Europe, and is now an advisor to Abramovich.
De Visser, who also recommended Arjen Robben to the Blues, has confessed that Messi’s name has been discussed in the past.
“I've always been a Messi fan, since he was a 13-year-old from Argentina and went to Barcelona. Messi is obviously a phenomenon and also only 27.
"In the past, the name of Messi has often been discussed at Chelsea, but he was always too expensive. If Roman Abramovich really wants him, he can of course do anything.
"But whether he's serious, I cannot say. I'm in Ghana and I have had no contact with the club for a while. If I knew, I would indeed not be allowed to talk to the press.”
Messi has distanced himself from speculation over his future and stated recently that he was committed to the Barcelona cause.
He commented that reports that he wanted to leave Camp Nou were ‘lies’.
