Mark van Bommel will wait until the end of the season before deciding his next move.
Van Bommel swapped Bayern Munich for AC Milan in January and the Rossoneri retain the option to extend his five-month deal for a further year.
Should that not happen, Van Bommel is likely to have plenty of other options with former club PSV Eindhoven and Tottenham known admirers.
The 33-year-old's representative, Mino Raiola, told Voetbal International: "There is still nothing certain - only that PSV are the only Dutch option for him.
"If Milan were deciding today they would keep him. He is a very important player for them, but as he only came in the winter window we decided together that only in May would we look to the future."
Meanwhile, reports in Russia suggest Anzhi Makhachkala could look to sign Gennaro Gattuso at the end of the season.
Anzhi, who have signed Roberto Carlos and made an attempt to bring Ronaldo out of retirement, are believed to be keen to add another star name to the squad. A source quoted in the Russian media said: "Now is the right age to think about the end of his career and to sign an advantageous contract."
