Jamie Vardy's first-half dismissal, and Leicester's subsequent disciplinary meltdown, did not prevent the defending Premier League champions from collecting what could be a season-changing point at Stoke.
Referee Craig Pawson dismissed Vardy in the 28th minute for a challenge on Mame Diouf where the England global, jostling with Glen Johnson, left the ground with both feet before returning to the turf by the time he won the ball.
With Pawson's first-half performance prompting such frustration in the Foxes' ranks, the typically placid Ranieri had to be dragged away from the referee by Kasper Schmeichel at the interval, yet when the full-time whistle went, the Italian was back fist pumping in front of the travelling support.
The game had been billed as a duel between the two Spanish global strikers Negredo and Swansea's Fernando Llorente, but the Boro man won hands down, scoring on 18 minutes with a lovely first-time finish from Adam Clayton's low cross. Opinions were fairly split on this one, but personally it seemed rather harsh, especially from a referee who only handed Marcus Rojo a yellow card for a cynical two-footed challenge against Crystal Palace midweek. Subs: Charlie Adam (for Bojan): 6, Ramadan Sobhi (Whelan): 5. Subs: Demarai Gray (Albrighton) 6, Leonardo Ulloa (Slimani): 7, Ahmed Musa (Mahrez): 5. King sends in a floating delivery from the left for Huth whose header forces Grant into a diving save. Bojan surged down the left and saw his cross blocked by Danny Simpson's arm, before sending Schmeichel the wrong way from the resulting penalty after 39 minutes.
The Spaniard calmly tucked the penalty away to make it 1-0, and from there Leicester completely lost their heads, a grand total of 5 players being booked for various offences in the remaining 9 minutes.
45'+2 GOAL! Stoke 2-0 Leicester: From the free-kick, Imbula's effort hits the post from the edge of the area, it bounces off the keeper's head and Allen is there to tap the ball into an empty net. Ulloa makes an instant impact, netting with a header which was just over the line despite Shawcross's clearance.
The Foxes are winless in their last 11 Premier League away games, failing to keep a clean sheet in all of those matches.
Stoke have not beaten Leicester at home in the top flight since December 1980.
