It was not a memorable performance, but Argentina got the win they needed, beating Mexico 2-0 at the Lusail Stadium to keep their hopes of qualification alive.
As is so often the case, Lionel Messi proved to be the difference after a first half in which his side failed to hit the target.
His goal from 25 yards out midway through the second half sneaked into the bottom corner to give the Albiceleste the lead and he would turn provider 23 minutes later, setting Fernandez up for a wonderful second.
Mexico were determined but lacked quality in the final third, with the result dropping them to the bottom of the section, while Argentina climb into second.
Mexico have lost all four of their World Cup games against Argentina – only Nigeria (5 vs Argentina) have played more World Cup matches against a specific nation while losing every time.
