A spokesman for the bar said: "We take the privacy of anyone in our bar extremely seriously and what has happened is very disappointing.

"In the first instance it's very rare that any altercations happen in the venue. We're a friendly bar and this is not something which happens regularly. It's very much an isolated incident.

"We'll work with the authorities to help in any way we can now.

"We've found out how the footage was made public and acted quickly to remove the person responsible from the company. He will be losing his job."

The spokesman added that they were satisfied with how staff and the bar's door team handled the assault.

"It was sorted out quickly from our perspective," he said. "The door staff did their jobs very well.

'There is always a good atmosphere here and we welcome anyone. We don't like to see things like this happen here no matter how infrequently."

Barkley, who is out of contract at Everton at the end of next season, faces an uncertain future at the club, with Spurs among those interested in signing the player.

He did not feature for England last month, despite being named in Gareth Southgate's squad, and criticised for his poor performance in the recent 3-1 Merseyside derby defeat by Liverpool at Anfield but he impressed against Leicester and set up Romelu Lukaku for a goal with an inviting cross.
