Leicester extended their lead at the top to seven points after Wes Morgan's fist-half header earned them a hard-fought victory against Southampton .
The Foxes skipper powered home Christian Fuch's cross from the left as Claudio Ranieri's men moved a step closer to the Premier League title.
However, Saints boss Ronald Koeman will feel aggrieved that the visitors were denied a penalty beforehand when Sadio Mane's goalbound shot struck the arm of Leicester defender Danny Simpson.
The win means Leicester need four wins from their remaining six games to wrap up the championship.
1. Leicester closing in on title
The Foxes' incredible story keeps on going after they opened up a seven-point advantage with only six games left.
Four more wins from their final six games will guarantee them the title.
2. Foxes grinding out the points
Claudio Ranieri's men recorded their fourth successive 1-0 win and their fifth in six games with this display.
It wasn't vintage as they rode their luck at times but just scoring against the league leaders is a feat in itself right now.
3. Christian Fuchs a steal
The bargain transfers of N'Golo Kante, Riyad Mahrez and Jamie Vardy have got a lot of praise this season but let's not forget the astute free transfer of Christian Fuchs too.
The Austrian international captain, 29, set-up Wes Morgan's goal and has been superb all season at left-back.
4. Southampton's clean sheets out of the window
Saints have now gone six games without keeping a clean sheet.
Prior to this run they had kept six in a row.
5. It's the chairman's birthday
In case you missed the giant banner in the ground or the fly-by from a plane trailing another banner, we can confirm Leicester owner Vichai Srivaddhanaprabha celebrates his birthday on Monday.
He gave fans free beer and donuts to mark the occasion.
