  The new CERN proton-proton collider, the LHC, is about to start in 2007 its
data taking. Millions of top quarks will be available out of these data,
allowing to perform a wide range of precision measurements and searches for new
physics. An overview of the planned top physics program accessible with ttbar
events is given for the ATLAS and CMS experiments. A particular emphasis is put
on the precision measurements of the top mass, top polarization and searches
for new physics in top production and decay.
