The Argentine, 34, has been out of action since midway through last season and delighted the travelling Nerazzurri supporters by coming off the bench to score twice.
This double means a lot to me, he told the club's official website. I'm delighted with my return and of course to score two goals as well.
We played superbly today and we've got a fantastic group of lads here. There are loads of people I'd like to thank: my family, my kids, my team-mates, Andrea Scanavino, who worked closely with me in this period, Franco Combi and other doctors, other people I wouldn't like to forget.
We really have got an exceptional group here and we're going about things the right way. Coming back into a team that's playing so well makes everything that much easier.
We must keep taking each game as it comes - that's what we're trying to do. We've got a new group of players and a new coach so there's lots of work to do but we're on the right track.
