However, Nantes boss Ranieri claims Lucas has opted for a different challenge, hinting a deal with United is already agreed.
"He's a high-class player, and with us he could have played in a league he knows instead of being a PSG substitute or going to another country," Ranieri told Le Parisien.
"He would have been available right now and could have six months away from the World Cup. But he made another choice. Never mind."
