The Belgium international has urged his team-mates not to lose focus as they have set their sights on winning the treble
The Bavarians comfortably sit atop of the league table, while they meet Wolfsburg in the semi-finals of the DFB Pokal, and will defend a 3-1 lead in their Champions League round of 16 tie against Arsenal next week.
Nevertheless, Van Buyten has stressed that they have not won anything yet and has urged his team-mates to keep pushing in their bid for silverware.
"Everybody now expects us to win every game. That's rather dangerous. We cannot afford to relax," Van Buyten was quoted as saying by Bild.
"We have to remain focused on each Bundesliga game, ideally two days before the match even takes place. Or you could all of a sudden end up playing a very difficult game...
"The games against Wolfsburg and Arsenal will be like finals for them, and they will approach those matches like that. We cannot afford to let up."
Bayern are currently preparing for their Bundesliga match against Fortuna Dusseldorf.
