Jermaine Beckford marked his return to the Leicester starting line-up with his first goal for the club as Sven-Goran Eriksson's side returned to winning ways with a 2-0 victory over Watford and moved to within touching distance of the npower Championship play-off places.
The club-record signing from Everton had a goal chalked off before finally breaking his duck in his sixth appearance since his deadline-day switch to the King Power Stadium with a well-placed header nine minutes before half-time.
Beckford's strike partner David Nugent opened the scoring after 19 minutes.
Leicester thought they had been rewarded for their bright start in the ninth-minute when Beckford's volley looped over goalkeeper Scott Loach, but the ball was adjudged to have gone over the left byline before Sol Bamba had dug out a cross.
Beckford was almost presented with another opportunity to score five minutes later when Loach came sliding out to collect Paul Konchesky's through ball. The one-time England squad member spilled the ball but Beckford was at too acute an angle to fully capitalise.
Konchesky was involved again when Leicester opened the scoring. A delightful first touch from Nugent when collecting Konchesky's pass took him past two defenders and into the Watford penalty area, where he sent a left-foot shot across Loach and into the far bottom corner for his fourth goal of the season.
Only a fingertip save from Loach on the half-hour denied Nugent a similar goal - this time from the right-hand side.
Leicester deservedly extended their lead in the 36th minute when Yuki Abe's right-wing cross was glanced home by the head of Beckford.
Eriksson's side were less of a threat after the break and did not really threaten again until the 78th minute. Substitute Darius Vassell, on as a replacement for Beckford, had a curling effort from inside the area deflected just wide. Bamba headed over from the resulting corner.
Jonathan Hogg worked Kasper Schmeichel for the first time in the 86th minute but the Leicester goalkeeper showed good agility to keep him out as he turned his volley over the crossbar.
