#4 Gonzalo Higuain (Argentina)
Gonzalo Higuain has been a prolific striker for his club Juventus in the past two seasons as he found the net 55 times in 105 appearances. His international career hasn't been as illustrious as he has been criticized for losses against Germany and Chile at the 2014 FIFA World Cup final and 2015 Copa America final respectively.
However, his clinical ability in front of the goal can't be ignored as he has scored 31 goals in his 70 appearances for La Albiceleste.
His attacking partner Paulo Dybala at Juventus is expected to link up well with him along with Argentine talisman Leo Messi once Sampaoli figures out a formation that allows the latter to play with Dybala. Higuain's aerial abilities and link-up play with teammates make his presence in the opposition box even more dangerous.
Having failed to score for the national team since October 2016, he will be determined to make a mark at this World Cup.
