Samaras and Bianchi have been loaned out to Celtic and Lazio respectively.
The duo will spend the rest of the season away from Eastlands after struggling to hold down regular places in the first team.
Eriksson is unsure if the pair will return to the club after their loan deals come to an end in the summer.
"It (the door) is open for them. We, as a club, hope they are going to do very well in Italy and in Scotland," he said on Sky Sports News.
"They are still on loan and after this season they might be our players again."
