Erling Haaland scored twice to eliminate Brazil from the World Cup, send Norway into the quarter-finals and tie the golden boot race.In a tournament that the superstars have dominated, Haaland, Kylian Mbappe and Lionel Messi all have seven goals. It is the first time in World Cup history that three players have scored as many. The record for a single tournament is still held by Just Fontaine, who scored a remarkable 13 goals in six games in 1958.It is turning into one of the all-time golden boot contests, with Haaland's Norway and Mbappe's France into the quarter-finals and Messi's Argentina playing Egypt in the round of 16 on Tuesday.So who is best positioned for the race? Our writers present the case.Lionel MessiLionel Messi is inevitable. Messi is the greatest of all time. Messi is unstoppable.As long as Argentina keeps progressing, Messi will keep scoring. It seems completely obvious to say that. He is the best ever to kick a football; he has scored more goals at World Cups (20) than anyone else, more goals for Argentina (124) than anyone else, and has scored in eight consecutive World Cup matches (another record).And yet, it's also a complete surprise to see him repel time and age to continue to write his own script at the age of 39. What he's doing has never been done before; we are in completely uncharted territory.He looks good for it. The team revolves around him, and he's dribbling and scoring in almost exactly the same manner as when he was 17.With seven Messi goals from four matches so far, Argentina, as expected (despite their humongous wobble against Cape Verde), should reach the semi-finals with victories over Egypt and then either Colombia or Switzerland. That means four more matches (with either a final or a third-place play-off to finish). With seven from four, how many could Messi score from eight? Double figures, last achieved by Gerd Muller with 10 in 1970, feels easily achievable. Perhaps even Just Fontaine's 1958 World Cup record of 13 will be in Messi's sights.
