Six days left before the start of the World Cup 2018, where the hosts, Russia, face Saudi Arabia in the 1st match of Group A. At this point, it would be interesting to analyze the impact of some environmental factors on the performance of the countries participating in the biggest sports event in the world. Every detail is significant at this stage of the tournament.

In Premier League, this season, there is a great variety of strikers with different game style and skills. Romelu Lukaku has the ability to displace the opponent defenders with his muscular physique, he takes advantage of the chances that his teammates create for him and creates his individual moments during the match on his own, too. Harry Kane is a real “killer” inside the box area and has a tremendous talent at the ball keeping when his team defends lower on the field. Alvaro Morata and Pierre-Emerick Aubameyang have also great scoring instincts and considered top-class strikers. In case of Roberto Firmino, he is reputed to be Center Forward, but there is no actual position on the field to describe the range of his skills and the support he provides both in offensive and defensive situations.
