The Roten icon hails the France international midfielder's contribution last season, while he believes that the Bundesliga will be a two-horse race again in 2013-14Bayern Munich would not have won the treble last season if it were not for Franck Ribery.
The Frenchman was voted Uefa's Best Player in Europe award following a successful 2012-13 campaign and the Roten hero has hailed the winger's role in Bayern's trophy haul.
"Without him, Bayern wouldn't have won the treble - one or two trophies perhaps, but not all three," Beckenbauer told Fifa's official website.
"Franck Ribery made a huge contribution. He's one of the best in the world in any case and this year he was the best."
Beckenbauer then went on to discuss Bayern's Bundesliga chances this season and made it clear that that he expects Borussia Dortmund to make things hard for FCB.
"Borussia Dortmund are stronger now and they certainly won't allow Bayern to run away with it by such a huge margin again," he continued.
"It'll take a few more weeks or even months before Pep Guardiola is satisfied, because the players haven't yet completely adapted to the style of play the coach wants. That's completely normal, and it always takes time.
"Whatever, I'm looking forward to an exciting season and I think it'll end the way it did last time, with a two-horse race for the title between Borussia Dortmund and Bayern Munich."
Bayern currently sit second in the Bundesliga table with 10 points from four games, trailing Dortmund by two points.
