Scout report: How Walsall's eight-goal striker and talented youngsters will eye revenge against Sunderland
The Saddlers will be something of a familiar test for Jack Ross' side given the pair met as recently as last weekend but, given the Black Cats' late heroics that day, Walsall will no doubt be keen to right the wrongs.
So what should Ross and Sunderland expect this weekend?
Here's an in-depth look at the Saddlers

The front line is very much based on youth, with a clutch of promising youngsters starting to flourish.
Further back, however, the Saddlers benefit from some real experience with the solid bank of four at the back proving difficult to penetrate.

In the centre of the park, youngster Liam Kinsella has impressed in recent weeks after injuries presented him with an opportunity.
