Nottingham Forest may be in the division below West Ham, but the two sides' contrasting form means it's the Championship side who head into this third round FA Cup tie as favourites. Forest are currently sitting in a playoff position, and once again are in the hunt to win promotion to the top flight.
That's in stark contrast to West Ham's problems near the bottom of the Premier League table. Sam Allardyce's side lost 2-1 to fellow strugglers Fulham in their last game, and have fallen to second-bottom with just 15 points from their opening 20 matches. There's no doubt that Big Sam is feeling the heat.
Allardyce is still hampered by an injury-ravaged defence, with centre-backs Winston Reid, James Tomkins and James Collins all out, meaning that the Hammers could be forced into playing a back four formed entirely of full-backs. That isn't where their injury troubles end, with forwards Mladen Petrić, Ricardo Vaz Tê and Andy Carroll also still out, and midfielder Kevin Nolan suspended. For Forest, David Vaughan and Djamal Abdoun are doubtful.
