The referee list of Arsenal and Liverpool in the first leg of the League Cup semi-final on January 6 was announced, and the referee was Oliver, who has enforced Arsenal's most appearances this season.

David Oliver will be Arsenal's referee against Liverpool on Thursday night.
The VAR officer is Darren England.
While we haven't paid much attention to referees in the League Cup this season, oliver has played in seven Arsenal games in the Premier League – 4 referees and 3 VAR officials.
He has played in a 4-0 away defeat to Liverpool – Liverpool's only game this season, Arsenal beating Norwich, Arsenal's win over Leicester City and a 4-0 away loss to Liverpool.
Darren England has played for Arsenal twice as a VAR official.
A total of 24 referees have played in the Premier League this season, and Arsenal have already met 12 of them. Oliver played four games, twice as many as the other five referees: Atwell, Mike Dean, Atkinson, Anthony Taylor and Bowson.
Oliver came in second in terms of number of VAR officers, playing in three Arsenal games, with Chris Kavanaughaner topping out four times.
Most Arsenal fans know and dislike referee Jared Gillette, who has served as a VAR officer 3 times.
Atwell, England and Banks have served twice each.
Dean, Marina, Mason and Whitestone each served once.
Brooks, Harrington, Coote, Madry, Hooper and Salisbury have so far not served as referees or VAR officers for Arsenal matches in the Premier League.
