The Brazilian's representative has confirmed that the defender is having a medical at San Siro ahead of a loan move to the Serie A side, prompted by work-permit concerns
The Brazilian, who joined the Blues from Fluminense in January, is set to move to San Siro for the 2013-14 season as Inter look to improve on their ninth-place finish last term, with Jose Mourinho having noted in July that a lack of work permit this season would necessitate a temporary spell elsewhere.

"He is undergoing his medical right now [on Tuesday]," agent Frederico Moraes told TuttoMercatoWeb.
"Wallace is truly very happy that things all went for the best and now he just wants to wear the Inter jersey as soon as possible."
The 19-year-old right-back is poised to become Mazzarri's 12th recruit of the transfer window since leaving Napoli in May to take over from Andrea Stramaccioni.
The Nerazzurri coach has brought in centre-backs Rolando and Matias Silvestre, while Diego Laxalt, Mauro Icardi and Ishak Belfodil have been added to the forward line.
Inter start their Serie A campaign with a home game against Genoa on August 25.
