The Everton manager, Marco Silva, says goalkeeper Jordan Pickford has been reminded of his duties and obligations after being caught up in a disturbance in Sunderland at the weekend.
The England No 1 appeared to be involved in a fracas in the early hours of Monday morning.
Northumbria police and Everton are investigating the incident, and Silva made it clear on Friday he is “not happy” about it.
“If you ask me as a manager I am not happy with what happened,” the Portuguese said. “Football players have duties and obligations. It is a matter for us to remind him and everything we must do we already did.
“The first chat of the week I was clear with him. Everything is clear in his mind about his obligations. It is my expectation it won’t happen again. No one is happy with the situation, it was not a good thing. The matter is finished in this moment.”
