FIFA World Cup 2018: 5 big-name footballers that could disappoint 

#4 Mario Mandzukic

Croatia's scorer

For starters, he is 32-years-old and is not a goal-scorer anymore, which is precisely why he plays on the left as an auxiliary forward and the first line of defense. In this role, he is magnificent; of this, there is no doubt.

For Croatia, however, he is the central striker and his role at Juventus is played by Ivan Perisic in the national team.

As a result, the bulk of the scoring duties will be on his shoulder, but the truth is that he is not as great a scorer as he once was. Ever since joining Juventus, the highest number of goals he has scored in a season is 13.

This season, he scored 10 goals from 38 matches and played more of a support role for the other forwards.

And that doesn’t bode well for him in Russia.
