The German outfit wrapped up the Bundesliga title with a 3-1 win over Hertha Berlin on Tuesday.
Despite already clinching the honour, Guardiola wants his side to remain focused on facing Hoffenheim this Saturday.
"We want to keep going," Guardiola said in a press conference. "I don't think it's necessary to say that to the players.
"We need to play as much as possible to prepare for the quarter-final in Manchester. I don't want the players to think about the Champions League."
Bayern will travel to Old Trafford for the first leg against United next Tuesday.
