On 4 May 2016 FC Basel announced that they had signed Riveros on a five-year deal. Due to Riveros commitments with the Paraguay national football team in the Copa America, he was not be expected to join the Basel first team until the beginning of July. Riveros made his debut for his new team on 15 October 2016 in the home game against Luzern. The game ended with a 3–0 victory and Riveros played the full game.
Under trainer Urs Fischer Riveros won the Swiss Super League championship at the end of the 2016–17 Super League season. For the club this was the eighth title in a row and their 20th championship title in total. They also won the Swiss Cup for the twelfth time, which meant they had won the double for the sixth time in the clubs history.
On 28 May 2016 Riveros made his debut for the Paraguay national football team against Mexico and he played the full game. He was named in Paraguay's squad for the Copa América Centenario. He failed to make an appearance, however, as Paraguay were eliminated at the group stages without having recorded a win.
