AC Milan are eyeing Japan fullback Gotoku Sakai.

Sakai has enjoyed an outstanding Bundesliga season on-loan at Stuttgart from the J-League's Albirex Niigata.

Sky Italia says Milan have the 21 year-old defender under consideration as cover for Ignazio Abate.

The stumbling block is Stuttgart, however, which have the option to sign Sakai permanently at the end of this season.
