PARIS: Argentina got its men's Olympic football campaign back on track with a 3-1 win over Iraq in Lyon on Saturday. One of the pre-tournament favourites, Argentina suffered a surprise 2-1 defeat to Morocco in their opening Group B match, marred by a pitch invasion by Moroccan fans and a two-hour delay. While Iraq threatened another upset when Aymen Hussein equalised in first-half stoppage time, goals from Luciano Gondou and Ignacio Fernandez sealed victory for Argentina.
