Arturo Vidal has refused to be too critical of Bayern Munich after they were held to a goalless draw by Eintracht Frankfurt on Friday night.
Bayern were searching for an 11th successive Bundesliga win since the start of the new season, but Frankfurt produced an impressive defensive display to keep the leaders out.
However, Vidal believes that Frankfurt deserve credit for limiting the opportunities on offer to them.
"It was a really tough game and it's almost impossible to score in a match like that as they had all their players around the box," the Chilean midfielder told the Bundesliga's website. "We worked well as a team and need to keep working hard now.
"We're not tired after so many games recently; we're in good shape physically."
Bayern now switch their focus to Wednesday's Champions League meeting with Arsenal.
