Paulinho came on as a second-half substitute and powered his way into the box before netting from a tight angle.
Luis Suarez had a penalty claim turned down after tangling with Djene Dakonam in the box, ultimately earning himself a booking after continuous dissent.
Argentina global Lionel Messi nearly levelled the scores just before the break but his brilliant free-kick, that seemed destined for the top-left corner, was superbly tipped around the post.
