The Argentine veteran believes the Catalans' biggest problem will be to adapt when the likes of Lionel Messi and Andres Iniesta retire and insists he wants to continue playing
The Catalans romped to the Liga title last season despite spending much of the campaign without boss Tito Vilanova, who was forced to spend time recovering away from the club due to a cancer relapse.
Riquelme, who was at Camp Nou between 2002 and 2005, believes the club could struggle when the likes of Lionel Messi and Andres Iniesta call time on their careers, but maintains the squad has enough quality to cope without a trainer.
"Barcelona play just as well without a coach," he told TV programme Despertate.
"Last season the coach was out for a few months and they became champions with five games to spare. Barca will have a big change when Xavi, Messi, Iniesta, [Carles] Puyol, [Sergio] Busquets and [Gerard] Pique are not there, but the group that doesn't go can play without a coach."
Riquelme went on to stress his desire to continue playing despite his contract at Boca Juniors expiring next summer.
"I'll sit down with the president, as mates, and in 30 seconds we'll arrange it. If they want me to continue, I'll continue, and if not, nothing will happen. I'll look for somewhere to play. But after June 30 I want to continue," said the 35-year-old.
Finally, the midfielder, who has 51 caps to his name for Argentina, has backed Alejandro Sabella's side for glory at the World Cup next summer due to the wealth of attacking talent at their disposal.
"We have the luxury of not calling on [Carlos] Tevez, so you can imagine the forwards we must have," he added. "If things are good at the World Cup, we will be favourites to win it."
