Oliveira (pictured) found the net for third time in two games but although his team looked the more imaginative in flashes, it was the side the midlands who had the upperhand in terms of possession and half-chances. Neither side could find a cutting edge however and that was reflected in a quiet night for both keepers. 
It was Chelsea who caused the first panic in the opposition area, Leicester keeper Peter Akman struggling to punch out under pressure from Adrian Pettigrew. But shortly after that, Leicester drilled a free-kick into Pidgeley's side-netting and then caused trouble with a long throw that was allowed to bounce deep in the area, Louis Dodds hooking over.
Leicester's James Wesolowski was booked for a heavy tackle on Nuno Morais, Danny Woodards following with a caution soon after for dissent. Pettigrew was the other yellow card of the game, shown for a second-half tackle from behind.
It took Steven Watt to be in the right place at the right moment to stoop and head a dangerous ball away from Dodds and then after two failed attempts to clear the resulting corner, Ashley Chambers flashed his volley well off-target. In a Leicester team of mostly youth team-aged players, Chambers was by some way the most junior at just 14!
Dodds was off-target twice more before the break as Leicester continued to dominate the half-chances.
The Chelsea goal came in stoppage time. The ball, originally won at the back by Tillen and Grant, was patiently worked up the pitch until Morais swung it over from deep to the far-post area. Woodards leap to win a header was a prodigious one, the key to the goal, and Oliveira, who had been involved earlier in the move was on-hand to turn the knock-down in.
Leicester's second-half fight-back began with Levi Porter driving into the side-netting after missed challenges by Watt and Pettigrew had left an opening.
Midway through the half Anthony Grant burst out from deep midfield and tried his luck from distance but lacked power. Substitute Filipe Morais, on for Seb Kneissl who was hampered by a troublesome foot, drove across the face of goal after collecting Oliveira's cross-field punt.
The Chelsea defence stood firm for most of the second period, registering a fourth successive clean sheet but unlike away fixture, they were grateful not to lose the lead in the dying minutes when Billy McKay lifted the ball onto the roof of the net after confusion in the rearguard.
After the game coach Mick McGiven gave his analysis. He said: “We didn't create much and it was a scrappy game. The final ball was disappointing and the keepers have barely had a save to make but it is another win. A hard fought victory. The boys looked a little tired so we may have to modify what we are doing in training.”
