St Helens boss Kristian Woolf on BBC One:

Asked if Saints are seeking revenge after losing 2019 Challenge Cup final: "No, not at all . It is a different season and a different season in every way. Obviously things are a littler different at the moment.

On the game: "We know it's a big game and a great challenge. They are in really good form and we are good form. It is going to be a great day."

Warrington Wolves head coach Steve Price on BBC One:

"There is big excitement going round the group.

"We have been playing some really good football, we have a lot of confidence and that makes for a good game today."

On have a number of players isolate because of Covid-19 protocols in recent weeks: "It hasn't been easy. But those guys who have been out are profession rugby league players and six of them have played for their country, so they know what it takes to get the job done."

In case you missed what went down in the Challenge Cup quarter-finals last night, we've got you covered.

Dan Sarginson's try in golden point-extra-time saw Salford beat Catalans in the first of last night's ties.

Meanwhile, Leeds joined Salford as they cruised their way into the semi-finals with victory over Hull KR.

Are we in for a treat of fixtures this afternoon and who will be joining them in the last four?

Salford's AJ Bell Stadium home plays host to today's two Challenge Cup ties and there's had to be a bit of a rethink with regards to changing rooms, as the coronavirus restrictions continue to be in force.

As such, Saints will be getting changed in a unique position this afternoon with the concourse being available.

As we've said, today sees a repeat of last year's Challenge Cup final.

You can relive that day by clicking play on the video below.

Rejoice Wire fans. Watch with gritted teeth, Saints fans..

So, with the season ravaged by the coronavirus pandemic, these quarter-finals are taking place just a bit later than usual.

In fact the entire competition would have been decided several months before today's date had the virus not reared its head.

The Rugby Football League opted to redraw the sixth round after Toronto, who also withdrew from Super League for this season, were joined in pulling out by Championship sides Featherstone Rovers, Sheffield, Widnes and York, as well as League One club Newcastle Thunder.

After a delay to last week's Hull v Castleford sixth-round fixture due to players testing positive for the virus, it's full steam ahead for the quarter-finals.

Another day, another Challenge Cup quarter-final double header to get our teeth stuck into.

And what a set of fixtures we've got, with a repeat of last year's final to whet the appetite as Warrington take on St Helens.

After a sterling performance in the sixth-round last week, Hull FC take on Wigan in the day's second fixture.

And you can watch, listen and follow all the action on this page. Tremendous.
