Boruc is set to leave Fiorentina this summer and having spent five years at Parkhead earlier in his career, he would be interested in a return to Celtic.
“I have said that when I think of Celtic I think of warmth and love,” Boruc said in the Daily Record.
“But at this moment I want to play in a better league and aim for the highest target.
“As for Celtic, though, I would always consider a proposal from them.
“What is really important in my life is my family and I would listen to what they have to say because I need them to be happy.
“I have enjoyed my time in Florence but it seems to me that this is not my league. I would like to go and play in a better one.”
