Zidane's positive has put Real Madrid on alert, because the coach has permanent contact with the entire squad. Despite this, within the club there is security and trust in the protocols and they believe that this circumstance should not affect anyone else. The players pass daily checks, just like the French coach. Furthermore, Zizou did not come to Valdebebas this morning. Another important factor is the fact that during sessions he uses a mask to address his players.
On the other hand, it is also not believed that Zidane's positive occurred in Alcoi, one of the regions most affected by the coronavirus in recent weeks. The Cup match was on Wednesday, so If the contagion had occurred there, it is unlikely that the Frenchman would have tested positive so soon.
In this way, in the club they think that the contagion of the French coach occurred in the private sphere (it must be remembered that he was recently isolated by a contact with a positive). Obviously, it is impossible to know exactly where it was infected, but with the strict protocols that are followed before each training session and each game, it is very difficult for it to occur there. This gives peace of mind that there may be more infected staff members, since since the positive was known the coach isolated himself.
In the past, other Madrid players have tested positive (Hazard, Casemiro …) and no one else in the squad was affected. That reinforces the theory that the protocols are working and nothing suggests that in Zidane's case it will be different.
