Barcelona have seen a €35 million offer for Fabregas rejected but it is believed that the midfielder has made it clear to Arsenal he feels the time is right to return the club he left as a 16-year-old in 2003.
Xavi, Carles Puyol and Gerard Pique have all spoken of their hope that Barcelona will reach agreement with Arsenal and Messi is also keen to link up once again with a fellow graduate of Barca's La Masia academy.
"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.
"It would be special to be reunited with Cesc in the same team, in the same way that it happened with Pique when he returned from his spell at Manchester United.
"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 Pique left. For us to be together again would be special, a lovely situation for those of us that were there back then."
