Leicester 2-2 West Ham
Leicester showed impressive character, quality and resilience to recover from Jamie Vardy's sending-off and a West Ham comeback to eke out what could prove a crucial point in the race for the Premier League title.
Claudio Ranieri's men were supposed to be relegation fodder and odds of 5,000/1 underlined just how unlikely a title tilt looked to be, yet this has been one of the most incredible seasons in English football history.
The King Power Stadium faithful went through the whole gamut of emotions after goalscorer Vardy's controversial dismissal paved the way for West Ham to go ahead through Andy Carroll's spot-kick and a wonderful Aaron Cresswell strike.
"We must believe every time and this point is very very important, psychologically. After 2-1, to go back in the last minute, it's very very important" - Claudio Ranieri
But Leonardo Ulloa's stoppage-time penalty secured the Foxes a 2-2 draw.
The draw stretches Leicester's lead over second-placed Tottenham to eight points, but Mauricio Pochettino's men can cut the gap at Stoke on Monday as an amazing campaign heads towards a dramatic ending.
This never looked like being a straightforward afternoon after Kasper Schmeichel pushed a Cheikhou Kouyate header on to both posts inside the opening seconds before Vardy opened the scoring in the 18th minute.
However, the England striker's sending-off for simulation early in the second half blew the game wide open, with Winston Reid clipping a post.
Referee Jonathan Moss then further angered the home support by adjudging Wes Morgan had fouled the Hammers defender in the area.
Substitute Carroll slotted home the resulting spot-kick in front of watching England manager Roy Hodgson, who then saw uncapped left-back Cresswell highlight his quality with a sublime strike across goal and into the roof of the net.
There was another twist to come, though, as Moss pointed to the spot at the other end after ruling Carroll had taken down Jeffrey Schlupp and Ulloa held his nerve to equalise and send the Leicester faithful into raptures.
Ranieri acknowledged Vardy's red card had had a big impact on the game, telling Sky Sports: "It was a difficult match - very, very tough. We were lucky in the first minute when they had a chance that touched two posts. After, we scored a goal, played our football against a very good team.
"We lost a chance at the beginning of the second half when Okazaki made a cross and Vardy was very close to finishing the action. And then after, the sending-off changed the match."
On Moss' display, he diplomatically said: "I judge my players, not the referee. The referee watched this, it's okay. If some player doesn't play well, makes some mistakes, I speak with them and we try to improve their performance. But the referee is not my matter."
The Italian was delighted with the spirit shown by his players to salvage a point, saying: "Fantastic, fantastic. This is our soul. We play every match like this - blood, heart and soul. It's magnificent. I say 'thank you' to my players, the fans.
"We must believe every time and this point is very very important, psychologically. After 2-1, to go back in the last minute, it's very very important."
