In a situation where countries all over the world are reporting record-breaking numbers of new Covid19 cases, maybe travelling all around the world for these kind of national games is probably not the best thing to do ... I am sure Salah won't be the only one coming home with an infection. These national games are the perfect spot to spread the virus. Players from many different teams, from different countries come together, some probably from places that don't have these strict hygiene rules. No wonder that you have a high risk of getting the virus there.
But it is a compulsory match to play in this national event. Many are also worried about this, therefore the spread will continue to widen seeing so many cases in various regions especially in the simultaneous qualification that the possibility of the league players will return for those who are called by the national team. but I hope that in this situation they apply it so strictly that when they return to the league nobody gets infected under any circumstances.
