Who do u think will replace Maldini?!

since we are now few weeks till the end of the season, and all talks about Maldini retiring and this season could be his last one ..
Who do u think guys could repalce him ( not that there's any player could ever fell his place) but u know life goes on ...
who i think would be the best is zambrotta he is really amazing player he said once in interview he would love to come back to italy and would love to play with Milan.. but i don't know if barcalona would let him go after good season he played with them !!!
