Chelsea have condemned the "abhorrent" online racist abuse received by defender Wesley Fofana and say that it "will not be tolerated".
On Monday, Fofana, 24, shared to his Instagram story screenshots of six racist messages sent to him following Chelsea's 1-0 defeat by Arsenal in the Premier League on Sunday.
Arsenal felt Fofana was fortunate to remain on the pitch after committing several fouls at the Emirates Stadium.
"Chelsea Football Club is appalled and disgusted by the recent rise in online racial abuse towards our players," a statement from Chelsea read.
"The abuse Wes Fofana has been subjected to following yesterday's fixture is abhorrent and will not be tolerated.
