Lionel Messi delivered a vintage performance against Algeria, reminding the world of his elite status, but a rash tackle sparked debate among fans.
The Argentina captain produced a record-breaking display, scoring a hat-trick and moving to the top of the World Cup's all-time scoring charts, tying with Miroslav Klose on 16 goals.
However, a challenge on Aissa Mandi in the 31st minute raised concerns, with some questioning whether Messi escaped a possible red card.
Despite no sanction from the referee, the incident became a talking point from an otherwise unforgettable night for Messi, who also showed concern for Mandi after the challenge.
Lionel Scaloni warned against complacency, saying Argentina know any team can beat them if they become overconfident, but expressed confidence in the team's ability to perform well.
