Everton shirt sponsors SportPesa have apologised for celebrating Arsenal's victory on Sunday.
African-based betting company SportPesa, who agreed a "multi-year agreement" to be Everton's "main partner" in May, appeared to revel in Arsenal's victory with a tweet sent from its account which in part said: "Well in #Gunners! A superb gift by the players for the birthday gaffer! #MadeOfWinners."
The post has since been removed from the SportPesa account and it has apologised in a statement it addressed to Everton fans on Monday.
"We have to be honest in admitting that the tweet you say yesterday should never have gone our and we are deeply sorry for any offence this has caused," it wrote.
"We have reviewed and will revise our internal policies and processes, especially in relation to our other partner clubs, to ensure that this never happens again. We will up our game."
