Leicester City (0) 0
Shrewsbury (1) 1
Leicester City suffered the proverbial giant-killing as they were dumped out of the Capital One Cup second round by League Two side Shrewsbury Town.
Nigel Pearson had said there would be no sentimentality when his City side welcomed his first professional club to the King Power Stadium. And he was right.
Shrewsbury came with a purpose and, thanks to a first-half goal direct from a free-kick by Andy Mangan, pulled off an unlikely shock.
But no-one could say the Shrews did not deserve their victory.
There were echoes of City's 4-2 defeat to Burton Albion at the same stage two years ago with the hosts well off the pace and the lowly visitors giving it their all.
Nigel Pearson had made eight changes to the side that performed so admirably at Chelsea, handing out four debuts.
Ben Hamer made his first start in goal, while City also fielded a very inexperienced central midfield partnership of Michael Cain and Ryan Watson.
James Pearson, Nigel's son, also made his debut
It took City just 30 seconds to test Jayson Leutwiler in the Shrewsbury goal.
Straight from the kick-off, Gary Taylor-Fletcher brought down a high ball on his chest, fed Chris Wood, who in turn played in Riyad Mahrez on the right.
The Algeria international fired low towards the far corner but was denied by the strong boot of Leutwiler.
But the Shrews are unbeaten in League Two this season and, having knocked out Blackpool in the first round, showed no fear against an, albeit understrength, City side.
There was to be no quiet night for Hamer in the City goal, then, who had to be alert to tip over a stinging effort from James Collins before again showing sharp reactions to deny a rasping long-range drive from Mickey Demetriou.
If anything, it was the visitors who edged the early stages, with 20-year-old Jordan Clark pulling the strings "in the hole" for Shrewsbury.
City, lacking their usual fluidity, still had their moments, though, with Marcin Wasilewski volleying straight at Leutwiler from a teasing Mahrez free-kick, before Wood rattled the bar with a header but the ball landed the wrong side of the line.
No-one, though, could say that Shrewsbury did not deserve their lead when, following a clumsy challenge from Taylor-Fletcher on Collins on the edge of the area, Mangan curled the ball superbly past a sprawling Hamer.
And Shrewsbury should have been two up on the stroke of half-time when Demetriou found himself completely unmarked inside the City six-yard box.
Luckily for the hosts, though, the moment seemed to get the better of him and he scuffed his effort wide.
City managed a brief flurry in first-half added time with Liam Moore sending a diving header over the bar before Knockaert stung the palms of Leutwiler.
The second half continued in much the same vein as the first, with Shrewsbury having the first shot of the half, Vernon's half-volley straight at Hamer. Demetriou's whipped ball almost found Collins at the back post moments later but sturdy defending from Moore snuffed out the danger.
Hamer, who had suffered the odd wobble in pre-season, was City's standout performer, complementing his shot-stopping of the first half with some confident cross-claiming in the second.
However, he had to rely on his post to come to his rescue twice in the matter of seconds as Collins' low drive rattled the bottom of the upright, fell straight to Vernon, who somehow fired the rebound against the same spot from six yards.
It was then City's turn to curse the woodwork as substitute David Nugent drove the ball past Leutwiler, but back out off the post. Luck, again, did not fall their way when the Shrews keeper punched a corner off the back of his own defender but saw the rebound go harmlessly wide.
City threw all they had at Shrewsbury late on, Knockaert driving hard towards the byline, pulling the ball back for Nugent but his ball was just too far in front.
City had one final chance to send the game into extra-time when Wood put his header went a yard wide and, with it, went City's hopes.
