Fabregas has long been linked with a return to the club he left when he was just 16-years-old to join Arsenal.
“I would like to play with Cesc again because I know him like (Gerard) Pique (from the youth team),” Messi told Sport.
“We shared many things at that moment, when we coincided in Barca’s youth team, and I know what he can give on the pitch.
“We’re in contact. We speak and sometimes we send each other messages.
“He wants to come to Barcelona and we’re all waiting to see what will happen. I hope he ends up coming and that we can play together again.
“Nobody imagined that one day we could all be together in Barcelona’s first team, especially when Cesc and (Gerard) Pique left.
“For us to be together again would be special, a lovely situation for those of us that were there back then.”
