INTERIM boss Simon Rusk admitted it will be "a great honour" when he takes charge of Southampton in their Carabao Cup quarter-final against Liverpool on Wednesday evening.

Rusk, 43, has been placed in temporary charge while Sport Republic search for a permanent successor to Russell Martin, who was sacked on Sunday evening.

The current under-21s boss insisted he is only focused on facing Liverpool and is not currently thinking about Sunday's Premier League trip to Fulham.

"It's a great honour. I've worked at the club since the summer," Rusk said when asked about the pride he will feel on Wednesday evening.

"For me, concentrating on that as my focus is the right, professional thing to do. I'm sure there's always a period of reflection after.

"It will be a proud moment for me, without a shadow of a doubt. It's a great honour, you know. It's a great honour to represent the club and guide them into such an important game."

Saints will be without forward Adam Armstrong, who scored against Liverpool in the Premier League, due to suspension.

The 27 year old has been booked twice in the Carabao Cup this season - against Stoke City and Everton - earning him a one-game suspension.
