Roma director of sport Daniele Prade has moved to reassure fans Juan will not be leaving the club for Fiorentina this summer.
The Viola are in the market for a quality centre-back and Juan is now regarded as one of the very best in the world.
“I have not had any contact from Fiorentina. According to some people, we have already reached a deal, but I know nothing about this,” Prade told violanews.com.
“Juan will not be heading to Florence.”
Even so, Roma fans can expect a high profile departure this summer as the club is still in considerable financial difficulty.
Mirko Vucinic is attracting interest from Arsenal while Liverpool might yet replace Xabi Alonso with Alberto Aquilani.
Real Zaragoza's talismanic captain Alberto Zapater has flown to Genoa for a medical, which will complete his move to Italy if passed without complications.
The highly rated 24-year-old is regarded as one of Europe's best box-to-box midfielders and has attracted interest from Arsenal and Fiorentina.
Earlier this week, Genoa President Enrico Preziosi surprised the Italian Press by announcing a deal had been struck for Zapater.
“We have an agreement with both the club and the player, and I am very confident the deal won't slip out of our hands,” Preziosi said.
Zapater is being viewed as the perfect replacement for Thiago Motta, the Brazilian midfielder, who left for Inter this summer.
Diego Milito also joined Inter in that transfer, but not before lending Genoa a helping hand.
The Argentine striker used to play for Real Zaragoza and reports suggest he helped finesse a deal for young Zapater.
