The KNVB does not blame Feyenoord for the fact that the club does not yet test the players and staff members every week for the corona virus. Trainer Dick Advocaat said on Monday that the Rotterdammers only test when someone indicates that they have complaints.

Feyenoord did not seem to adhere to the protocol of the KNVB. It states that professional football players and staff must be tested for the corona virus at least once a week and in any case 24 hours before a match.

But a spokesman for the KNVB on Tuesday indicates to NU.nl that the teams only have to test weekly from two weeks prior to the start of the Eredivisie and Keuken Kampioen Division, and that it is therefore not yet mandatory.

"As long as they do it from two weeks before the start of the competition," said the spokesman. "We chose this because we want to ensure the progress of the competition. If you are found positive and need to be quarantined, you don't have to miss the start."

Infections at other Dutch clubs

At a press conference after the first training, the lawyer caused some controversy with his statements. He said, among other things, that Feyenoord's doctor, Casper van Eijck, does not fully agree with the protocol of the KNVB.

"Our doctor is very close to Erasmus MC and the virologists in the Netherlands," said Advocaat. "He says that we are only tested at the races, but only if we indicate that we feel something. He says that there is no point in taking a test otherwise."

The corona virus causes problems for a number of Dutch clubs. In the past week, infections were detected at ADO Den Haag (player and employee), Vitesse (attacker Hilary Gong) and Jong AZ (staff member).
