 note = {We show that the background field method (BFM) is a simple way of deriving the same gaugeinvariantresults which are obtained by the pinch technique (PT). For illustration we constructgauge-invariant self-energy and three-point vertices for gluons at the one-loop level by the BFMand demonstrate that we get the same results which were derived via the PT. We also calculate thefour-gluon vertex in the BFM and show that this vertex obeys the same Ward identity that wasfound with the PT.},
