Dave Woods is joined by former England half-back Kevin Brown and ex-Scotland hooker Andrew Henderson to preview the quarter-final ties in this weekend’s Challenge Cup.

It's fair to say any of the eight teams involved could lift the famous old trophy at the Tottenham Hotspur Stadium on May 28th. Plus, we also delve into what’s gone wrong at Warrington?

Time codes:

04:40 – They start with Hull Kingston Rovers v Castleford Tigers – Cas are starting to come good under Lee Radford.

06:25 – There’s now a real good feeling around Hull KR who’ve recently reacquired their stadium.

10:00 – What is going wrong at Warrington Wolves (who lost to Hull KR last weekend)?

15:00 – Can Warrington recruit to help them get out of their unexpected predicament?

18:00 – Catalans Dragons v St Helens – Saints have the best defence in Super League and Brown suggests the best ever in the Super League era.

21:10 - What’s the game plan to beat Saints. It’s suggested the Dragons are the only team that can stop them. And what influence can Sam Tomkins have.

27:10 – Wakefield Trinity v Wigan Warriors – appreciation of the new Wakefield coaching partnership of Willie Poching & Francis Cummins.

31:20 - A similar appreciation of Matty Peet, the new head coach at Wigan, whose team have got off to a great start.

34:10 – Wigan have the best full-backs in Super League in Jai Field and Bevan French. Brown thinks they could be the first side to play with two full-backs, changing the traditional style of play.

38:00 – Huddersfield Giants v Hull FC – This could be the tie of the round. Hull FC have players returning and look very strong, while the Giants have been very impressive so far this year.

42:30 – The Challenge Cup is as special now as it ever was – and playing the final at Tottenham this year is proving a real exciting prospect for the players.
