The leading model for the Gamma-ray burst (GRB) emission is the fireball
shock scenario. The collisions of fireball shells with the external
medium produce the afterglow emission, which is explained by a non-thermal
synchrotron radiation. This work demonstrates the scientific
interpretations of the multi-wavelength datasets obtained by GROND and
Swift/XRT for the afterglows of GRBs 080413B, 091127 and 091029, and
shows the increasing difficulties of the fireball shock scenario to model
the well-sampled multi-color afterglows observed with the latest
generation of GRB instruments
