After losing out on the Bundesliga title to Borussia Dortmund for two seasons in a row, Bayern Munich raced out of the blocks in this campaign to secure a massive 17 point lead over their rivals at the top of the league table.
Jupp Heynckes' men have been equally successful in their domestic cup run, eliminating Dortmund in the DFB-Pokal semi-finals on Wednesday.
Roth pointed out that Jurgen Klopp's men simply could not keep up with Bayern this season.
"[Wednesday] was a very intense game with a deserved winner in Bayern. This season, Dortmund are too small for FCB, and with the form they showed on Wednesday, the treble for Bayern is no illusion," he wrote in his column for TZ.
"Through the last two league titles, they [Dortmund] have incited Bayern to improve. This is a positive rivalry that will make both teams better."
Bayern sporting director Matthias Sammer credited their success over Dortmund to several key players.
"When we talk about leadership, I see Bastian Schweinsteiger, Dante, Philipp Lahm and Manuel Neuer as our core. They are world class, no question," he said to Spox.
"[Schweinsteiger] was very mobile, tactically excellent and he played with a charisma that has shown before but missed lately. The same goes for Dante and Neuer, and the incredible security they bring. Lahm has been world class for us for years anyway. This is important in these games that these players show their presence."
Despite the wealth of talent available to Heynckes, Roth advised the club's board to take Robert Lewandowski from their rivals once he becomes available.
"When the calibre of Lewandowski is on the market, then you have to strike," he noted.
"I do not believe [Mario] Mandzukic and [Mario] Gomez will be around forever. My opinion, you cannot have too much quality at this level."
