Manchester United could have two game-changers vs Liverpool

Who starts at left back?

Jonny Evans is out but Harry Maguire and Aaron Wan-Bissaka are back. Erik ten Hag has two specialist full backs available for the first time in a month, albeit two right backs.

Wan-Bissaka and Diogo Dalot started in the same XI against Tottenham the last time they were both fit in January. Wan-Bissaka actually lined up on the left as Luke Shaw was not deemed match-fit, so rather than relocate Dalot Wan-Bissaka was shoehorned in on the left.

Victor Lindelof has been the auxiliary left back of late but retaining him against Liverpool would be dicier than starting Wan-Bissaka, back after a two-month lay-off.

Which United will turn up?

United have won, drawn and lost against Liverpool in their three games under Ten Hag. Their victory was one of his sweetest and the 7-0 thrashing their heaviest defeat in the Premier League era.

A compact and disciplined performance at Anfield earned a creditable draw in December but a similarly reticent performance at home would be anathema to the Old Trafford natives.

An atmosphere for the ages?

This is the first domestic cup tie between the clubs with fans present since the League Cup third round in September 2013. It was lively at Old Trafford in the Europa League round-of-16 second leg in March 2016 and the presence of matchgoers will amplify the the occasion. More than 9,000 visiting fans will be in the away end.

On the United supporters, Ten Hag said: "They see it as a very big game, they are very eager for us to win this and I'm sure they will be right behind us.

"There will be more Liverpool fans so they have to be really loud, to support
