That was just one of a number of incidents that mired Chelsea’s 2-0 win at the Tottenham Hotspur Stadium.
Kepa narrowly missed being hit by the cup around the 65th minute mark, a few minutes before Chelsea defender Antonio Rudiger gestured that he had been the subject of racist abuse by some sections of the home supporters.
While investigations surrounding the Rudiger incident remain ongoing, Tottenham have moved swiftly to ban the cup-throwing fan.
In a separate incident, a Chelsea fan was also arrested for racially abusing Tottenham forward Son Heung-Min, who was red carded for raising his boots into the ribs of Rudiger following an aerial challenge.
Tottenham said in a statement issued on their website: 'We can confirm that we have identified and issued an immediate ban to the individual responsible for throwing a cup at Chelsea goalkeeper Kepa Arrizabalaga during Sunday's Premier League home fixture.
'We shall continue to take the strongest action possible against anyone found to be behaving in this way.
'Fans are reminded that our Ground Regulations state - the following acts are offences under the Football (Offences) Act 1991 (as amended):
- The throwing of any object within the Ground without lawful authority or excuse.
- The chanting of anything of an indecent or racist nature.
- The entry onto the playing area or any adjacent area to which spectators are not generally admitted without lawful authority or excuse.
'Our investigation into the alleged racist abuse against Chelsea defender Antonio Rudiger remains ongoing.'
Meanwhile, Tottenham have failed with an appeal to have Son’s red card rescinded, meaning the South Korean will miss upcoming games against Brighton, Norwich and Southampton.
