West Ham United boss David Moyes has defended Eric Dier following his altercation with a supporter in the stands after Tottenham's FA Cup exit to Norwich.
In the aftermath of the penalty shootout defeat to the Canaries, Dier climbed into the lower tier of the West Stand and confronted a fan, who is alleged to have been arguing with his brother.
The incident has split opinion with some backing Dier's decision and others claiming he was in the wrong to climb over rows of seats for a showdown.
"It is very easy to focus on the reaction of the player, and I don't think anybody wants to see players, coaches or anybody confronting supporters in that way," the Bournemouth boss said.
"But the world of football needs to look at what is said and what is acceptable and what is not acceptable.
"It is almost anything that is said from the terraces: 'Oh, that is just football banter, that is the world of football', but I don't think it should be like that.
"I think it is an opportunity to look at this and maybe review what is acceptable and what is not, highlighting it for everybody who goes to games."
Tottenham's investigation of the incident is on hold until Metropolitan Police finish their own enquiries, while the Football Association will also wait to see the outcome before acting.
