After getting fouled just outside the area, the forward took the free-kick, bending it beyond the reach of the goalkeeper with sublime effort.They won the game 2-1 to maintain their unbeaten start to the season.Messi's free-kick has only gone on to cement the impressive start to the season he has had with PSG. In his first full season at the Parc des Princes after joining last summer, he struggled to adapt to life in France. The Argentina captain notably stuck to providing assists last season. He provided 15 assists while netting just six goals in 26 Ligue 1 games for the Parisians.This season, however, has seen him score five goals in just nine games, only one goal shy of equalling his prior tally. For club and country, Messi has scored an impressive seven goals in just five games, which will only go to show that the 35-year-old is in brilliant form.PSG will be pleased that their front three have been sharp-shooting, with Neymar and Mbappe also snatching goals effortlessly in all competitions. The Parisians have scored a combined five goals in just two Champions League appearances so far. They will be expected to continue their goalscoring against Benfica. Ligue 1 has also seen the side manager an astonishing 28 goals in a mere nine games.
