Chelsea defender Antonio Rudiger told those responsible for racism in football grounds to "get some basic education" after he was the victim of alleged abuse during Sunday's 2-0 Premier League win at Tottenham.
After Rudiger's involvement in an incident which resulted in a red card for Spurs forward Son Heung-min during the second half, the Germany international told the match officials he had been targeted by apparent racism from the stands.
Between then and the end of the contest, a number of announcements were made over the public address system at the Tottenham Hotspur Stadium.
