The line-ups have been announced – so how will tonight's action go? Here are three potential keys to the game. A full scouting report appears in The Argus on every matchday.

1. BATTLE OUT WIDE: Reading’s threat comes down the wings. Jimmy Kebe and Jobi McAnuff are both real dangers. Albion make a change at full-back – but have brought back a danger man of their own Will Buckley plus more width on the bench. The wingers will be key men tonight.

2. CENTRAL MIDFIELD: The Royals are missing their first-choice duo of Jem Karacan and Mikele Leigertwood. Can Albion’s trio turn that to their advantage?

3. MAIN MAN: Experienced striker Jason Roberts has played a massive role in the Royals’ brilliant run. You can trace the start of their charge towards the top two back to their win against Bristol City on his debut. Albion must deal with his touch, pace and presence tonight.
