Munich - Bundesliga leaders Bayern Munich are determined not lose focus as a result of captain Philipp Lahm breaking his ankle, sport director Matthias Sammer said Wednesday.
"We have made a strong start so we will not be thrown off course by this further set back," Sammer told the Bild newspaper.
Bayern top the Bundesliga by four points from Wolfsburg and have already qualified for the knock-out stages of the Champions League.
Lahm, 31, suffered the ankle fracture Tuesday in training and is expected to be out for two to three months following an operation.
"We must not dwell on sentimentality and remain in a state of shock," Sammer added.
"From the beginning we have had contingencies to cope with many injuries."
Coach Pep Guardiola's squad has already been hampered with long-term injuries to Javi Martinez, Thiago Alcantara and David Alaba this season.
And midfielder Thomas Mueller is a minor doubt for Saturday's match with Hoffenheim having been substituted with a back injury in Germany's 1-0 win away to Spain on Wednesday.
