Brian Deane lifted Leicester to within one point of Division One leaders Portsmouth -for a couple of hours at least - by scoring the winner in the 2-1 victory over Watford at Vicarage Road.
This was just the sort of result the Foxes needed and it cemented their position among the automatic promotion positions.
Leicester were clearly eager to banish the memory of their 2-1 home defeat against Ipswich on Boxing Day and they had a fine chance to open the scoring after just two minutes, Paul Dickov firing an angled shot wide when well placed.
Jordan Stewart also drilled the ball off target for Leicester and Heidar Helguson had a volley held by goalkeeper Ian Walker, who was also made to work by the Icelandic striker after 13 minutes.
Helguson got in a close-range header but the former England man was equal to it.
Watford were causing problems with their aerial threat and after Paulo Vernazza had headed wide, Marcus Gayle rose to meet a Neal Ardley free-kick but could not find the target.
Helguson was proving a handful and sent another header wide before finding his range with his feet in the 29th minute. Jermaine Pennant sent in a good low cross and Helguson bundled the ball home from close range.
Leicester's early promise had evaporated but falling behind seemed to galvanise them, and Deane tried to equalise only to head a Muzzy Izzet free-kick over the crossbar.
But in the 34th minute they were level through Matt Elliott. The ball bobbled around the penalty area and fell to the Scotland international defender, who hit it low and true into the bottom left corner of the net.
The visitors had Andy Impey booked in the 39th minute for a foul on Pennant before Helguson went close to a second goal, heading over.
Deane had the last chance before the half-time whistle when he latched onto an Alan Rogers cross but volleyed wide.
The second period started disappointingly and on the hour-mark Leicester manager Micky Adams sent on Callum Davidson - returning after a hernia operation - and Nicky Summerbee in place of Billy McKinlay and Stewart to try and increase the threat from the flanks.
It produced the desired effect, but neither substitute was involved in the 66th-minute goal which put Leicester 2-1 up.
Instead, the Izzet-Deane combination produced the winner, the former England striker rising highest to head home the Turkey midfielder's corner.
Dickov almost increased the lead in the 73rd minute but Alec Chamberlain produced a brilliant save with his feet to keep out the Scot's volley.
From then on it was largely comfortable for Leicester, who also went close through substitute Trevor Benjamin and Deane, who could have walked off with a hat-trick.
