The end of Ramadan 2018 coincides with World Cup 2018's kick-off. It means that Muslim footballers will play in high-level football right after fasting for a full month. Not to mention that their training and friendly match before the tournament was done while they are fasting.

It's interesting to see Tunisia's goalkeeper action Mouez Hassen who faked his injury to allow his teammates to break their fast during friendly match against Turkey.

It is safe to say that fasting while playing gives disadvantages for professional footballers during match. Playing football requires a lot of energy and stamina, also dehydrate your body. As a professional footballers it is impossible to give your all in a game while fasting.

But many don't want to touch the issue because it's sensitive. Anything related to religion and personal beliefs is always sensitive. Even Liverpool FC's manager Jurgen Klopp refused to give comment about Mohamed Salah's fast before UCL final match.

According to Islamic teaching a man is allowed not to fast during Ramadan if he has a legitimate reason such as sick, traveling, and work that demands high physical labor. But some Muslim footballers don't want to break their fast due to personal beliefs.

There are at least seven countries with Muslim players majority in World Cup 2018; Saudi Arabia, Iran, Morocco, Tunisia, Egypt, Nigeria, and Senegal. It's interesting to see how they cope with fasting since some of them will be playing at the end of Ramadan.

As football fans, of course we hope to see the best performance of each teams playing.
