KIO questions UEFA's decision of breaching Step Two racism protocol
"We are encouraged that the protocol was initially enforced by the match officials, but UEFA must explain why players weren't sent to the dressing room during Step Two, as is clearly stated in the rules?" questioned KIO.
KIO wonders why the match wasn't called off
Pressing further on the issue, KIO mentioned that as per TV replays, racist chants continued even in the second half after a section of the fans had been ejected, and the match should have been called off.
"It's now time for UEFA to step up and show some leadership. For far too long, they have consistently failed to take effective action," KIO pressed further.
What is UEFA's three-step racism protocol?
As per UEFA guidelines, the following three-step protocol is to be followed in case of racial abuse during a match:
The first protocol involves an official announcement, via the PA system, inside the stadium, upon the referee's request.
The second protocol involves another announcement, with this time the abusive crowd section being cleared.
The final protocol involves the match to be abandoned.
UEFA's sanctions are not fit for purpose: KIO
KIO went on to say that the sanctions imposed by UEFA serve no purpose and called for harsher sanctions, other than pitiful fines or small stadium bans.
"If UEFA care at all about tackling discrimination - and if the Equal Game campaign means anything - then points deductions and tournament expulsion must follow," KIO asserted.
