For us, one of the most appealing bets available is centre-back Andy Butler at 28/1 to score the first or final goal.

The popular defender is always a threat when he gets forward and has one goal this season, from the clash with Blackpool in December.

Backline partner Andy Crosby, who is the club's penalty taker also looks a good bet at 22/1.

United's favourite for first goal is leading marksman Martin Paterson at 13/2, with fellow strikers Paul Hayes and Jonathan Forte 15/2 apiece.

The Addicks have a wealth of striking options, and the likes of Chris Iwelumo (6/1), Andy Gray and Luke Varney (both 13/2) are amongst the favourites.

Former Scunthorpe loanee Kelly Youga is 40/1 to net first or last.

The Iron are 15/8 to win the match, with the draw 9/4 and Charlton 5/4.
