Lionel Messi scored the opening goal for Paris Saint-Germain (PSG) in their Champions League clash against Benfica, but failed to take home all three points. While the visitors were chasing the winning goal in the closing minutes, manager Christophe Galtier substituted Messi, drawing the ire of angry fans on Twitter.Many of the 35-year-old's supporters strongly believed that the Argentine playmaker should have played the full 90 minutes. They did not mince their words as they took to Twitter to slam Galtier's decision to take Messi off the pitch instead of Kylian Mbappe or Neymar.Here is a selection of tweets from angry Lionel Messi fans:Johnathan 🗯️@mcjohnathan02You substitute Messi and leave mbappe on the pitch??

The entertaining draw between Benfica and PSG was held to just two goals after impressive performances from both the goalkeepers.The opening goal of the game was vintage Messi, whose curler put the ball past Odysseas Vlachodimos and into the top-left corner. The forward combined brilliantly with Neymar and Mbappe, passing the ball to the Frenchman, who laid it out for the Brazilian before it got back to Messi. Benfica became a record-extending 40th team that Messi has scored against in the Champions League.The visitors' lead did not last for long, as the Portuguese giants retaliated just minutes before half-time. A pinpoint cross from Enzo Fernandez into the far post led to a Danilo Pereira own goal.The second half saw PSG work ruthlessly to score another goal, however, the Benfica goalkeeper was impressive on the night. Both teams ended up settling for a point each, but will play again at the Parc des Princes next week.
