Marco Silva‘s side climbed to fourth place when they beat Arsenal 2-1 at Vicarage Road on October 14 but the Hornets have claimed just ten points from a possible 39 since then.
And although Watford are still in the relative comfort of tenth position in the Premier League, they are only six points clear of the bottom three. Nineteen points now separate Silva's side and top four, however.
Saturday's clash at the King Power Stadium is the second in quick succession between Watford and Leicester who met on Boxing Day with the Hornets running out 2-1 winners. That was the Golden Boys' last Premier League win.
Isaac Success and Craig Cathcart are gradually working their way back to fitness following long-term lay-offs while Tom Cleverley (hamstring) is expected to undergo a late fitness test ahead of Saturday's clash.
