The veteran defender is very pleased to have signed a new deal and is eager to help the Giuseppe Meazza side back to the top in 2013-14
The Argentina defender's previous deal was due to expire this summer and there were doubts as to whether Samuel would stay at the Nerazzurri after he made just 16 Serie A appearances in an injury-hit season last term.
However, the 35-year-old has now ended all speculation about his future by inking a one-year extension.
"I'm very happy to have renewed my contract for another year," the centre-back told the club's official website.
"Along with my team-mates, I hope I can give Inter a positive year and repay the club for the faith they've shown, since they still believe in me."
Samuel's contract extension comes only days after club icon Javier Zanetti signed a new deal until 2014.
