Palmeiras coach Gilson Kleina says he would welcome Juan Roman Riquelme to the club with open arms.
The 34-year-old playmaker has been without a club since leaving Boca Juniors in the off-season, and has been linked with several top teams in South America.
Kleina confirmed Palmeiras are interested in Riquelme, but warned the return of coach Carlos Bianchi to Boca could change things.
"Who would not want to have a player of his quality, especially for the Libertadores?" Kleina told Fox Sports.
"We have to see how the player is as he has not played in a long time. Now that Bianchi, who is a good friend of Riquelme, has returned to Boca, things have become complicated.
"All we can do is wait and hopefully we will welcome him to the club."
Boca's Bianchi also reaffirmed his interest in the player, but made clear that only Riquelme knows what follows next in his career.
"We will see what the chances are for Roman to come back. The decision is Roman's. I'll speak with him and see if he is prepared to return," he said.
"I know what Roman can give to the team. However, until I meet with him, I can't say anything else."
