Although the Bavarians were not crowned Bundesliga champions, with Borussia Dortmund defeating Stuttgart, they did cruise to a massive win at the Allianz Arena to put them within touching distance of the league title.
Speaking after the match, the Netherlands winger claimed Jupp Heynckes' rotation system was paying dividends for both himself and the rest of the squad.
"The fans saw a great game. It was one of those weird games that you don't experience often. We played very well, but Hamburg were also very weak and, quite frankly, we exploited them," Robben told reporters. "It's very good for the club now that there is a better squad [at the coach's disposal]. It's not just about the team on the pitch.
"The players are demonstrating a better rhythm on the pitch and it makes you feel stronger. Now I am back in top form."
Xherdan Shaqiri took full advantage of a rare start against HSV as he struck for the opener and assisted on another goal, and he hailed the versatility of the Bayern side after the game.
"You can see that almost every player is interchangeable. That has certainly been our key to success," Shaqiri said.
