"Everton is investigating an alleged incident of racist behaviour by a supporter attending today's fixture against Tottenham," read a statement on Twitter.

"Everton strongly condemns any form of racism. Any such behaviour has no place within our stadium, our Club, our community or our game."

The match was overshadowed by a sickening injury to Toffees midfielder Andre Gomes, who will undergo surgery on a fracture dislocation to his right ankle on Monday after falling awkwardly following a challenge by Tottenham's Son Heung-min.

Son was sent off having initially been shown a yellow card.
