  The top quark is the heaviest known fundamental particle. As it is the only
quark that decays without hadronisation, it provides the unique opportunity to
probe the properties of bare quarks at the Large Hadron Collider (LHC). This
article will present two recent measurements of the top quark using 13TeV
collision data with the ATLAS experiment: the top and anti-top quark pair
charge asymmetry measurement alongside the first test of lepton flavour
universality (LFU) of leptons to W bosons from tt events.
