The large W and Z cross sections expected at the LHC allow for several measurements involving electroweak bosons already in the early data. The W and Z cross sections can be measured with good accuracy with 10-100 pb-1. These cross-sections are presently predicted with about 5% uncertainty. The ratio of W and Z cross-sections in particularis not affected by the uncertainty on the machine luminosity and will thus be one of the first tests of the detector and analysis chain performance. The Z momentum and rapidity distribution measurements will quickly surpass the predictions in precision, and thus allow to constrain PDFs and QCD calculations. Also the W charge asymmetry will quickly become precisely measured. ATLAS strategies and expectations shall be discussed, using selected examples of expectations for measurements.
