I guess this is almost a local derby, with the two Clubs based just 40 miles apart.
Watford are managed by "Mr Cool" Slavan Bilic, while Reading have Paul Ince at the helm for the moment, though maybe not much longer.
Only 3 points separate the two teams in the table, Watford having the best of it with 9 points from their last 15, but Reading are on the slide, just 4 points from last 15.
The game will be shown live on Sky Sports.
