Wes Hoolahan scored twice as Norwich City won a seven-goal thriller in front of their biggest crowd of the season at Carrow Road.

In an amazing second half, Leicester substitute Matt Fryatt also bagged two goals but was sent off after scoring the second when he struck City defender Leon Barnett in trying to fish the ball out of the net.

Leicester were ahead in the second minute when a bad error by goalkeeper John Ruddy handed Martyn Waghorn the opening goal.

Andrew Crofts levelled after 31 minutes and City appeared to be in control when a Hoolahan penalty and Adam Drury's first goal since 2005 made it 3-1.

Back came Leicester with Fryatt scoring with his first touch, before a stunning goal by Hoolahan made it 4-2.

But the drama was not over as Fryatt struck again, only to be shown the red card after a tussle with Barnett in the back of the net.

Manager Paul Lambert replaced Chris Martin with Simeon Jackson, but there was a disastrous start for City when Waghorn gave the visitors the lead in their first attack after 78 seconds.

Waghorn cut inside from the right and went past Drury before firing in a left-foot shot that Ruddy somehow managed to spill into his own net at the near post.

It was a nervous start from City and moments later Ruddy had to gather a miskick from Ward that rolled goalwards.

Waghorn then brought Ruddy into action with a free-kick from outside the box but it was an easy catch for the keeper.

Drury produced the Canaries' first effort of the night when he moved on to Hoolahan's pass and struck a powerful left-foot shot that goalkeeper Ikeme turned over the top, not entirely convincingly.

Waghorn fancied his chances and let fly with a left-foot drive from more than 20 yards that flew past the angle of crossbar and post.

Ikeme was next called upon to pluck a goalbound lob from Ward out of the air as City pressed for an equaliser.

Lappin was shown the yellow card for a foul on King in the 24th minute.

Good work by Hoolahan set up a shooting chance for Lappin but his shot was blocked by Oakley and when Russell Martin collected the rebound, he was unable to get in a clean shot.

Jackson brought Ikeme into action with a header from Ward's cross, the keeper diving to his right to gather.

City drew level in the 31st minute when Crofts scored his third goal of the season.

Hoolahan crossed from the left and Jackson was unable to make clean contact with his header, but Holt retrieved the ball beyond the far post and turned it back for Crofts to score with a first time shot.

On the stroke of half-time, a cross from Waghorn whistled across the face of the goal with neither Barnett nor Russell Martin able to connect as they tried to clear.

• HALF-TIME: Norwich City 1, Leicester City 1

In the opening seconds of the second half, Hoolahan pounced on an error by Hobbs and forced Ikeme to dive to his left to save his long-range effort.

Lappin fired just over the top after Drury gathered a crossfield pass from Barnett and played him into space on the left corner of the Leicester penalty area.

City moved ahead eight minutes into the second half when Hoolahan scored his first goal of the season, from the penalty spot.

Korey Smith burst forward and found Russell Martin on the right, and the full-back's cross was blocked by the raised arm of King.

Referee Walton pointed straight to the spot and Hoolahan coolly tucked the penalty to Ikeme's left.

Another storming run by Smith set up the next chance for City as he found Hoolahan on the right and his cross to the far post was headed just wide by Holt.

Crofts fired high over the top as City sought to press home their advantage.

Jackson, who had had a quiet evening, almost made it 3-1 when he followed up on a blocked Lappin effort and his powerful left-foot shot was beaten away by Ikeme.

Smith was in an irrepressible mood and sparked another raid when he found Russell Martin, whose cross eluded everyone in the six-yard box but was retrieved by Lappin, who created space for a shot on his weaker right foot but fired into the side netting.

It was almost inevitable that City would add to their lead and they did so in the 62nd minute when Drury produced a delightful finish for his first goal since the Premiership season in 2005.

Leicester immediately reduced the arrears when substitute Fryatt scored within seconds of replacing Oakley.

Ruddy turned a Waghorn header round the post for a corner and the resulting flag-kick produced a game of pinball in the City area with Fryatt eventually forcing the ball home.

Ward and Crofts were booked for fouls as Leicester suddenly pressed for an equaliser, then Drury followed them into the book.

Chris Martin replaced Jackson before City restored their two-goal advantage with just over 15 minutes left with a brilliant goal by Hoolahan.

Holt teed the ball up for Hoolahan and after knocking it on with his left thigh, he struck a stunning half-volley past Ikeme from 25 yards.

There was real drama with 12 minutes left when Fryatt scored his second goal but was almost immediately shown the red card.

The substitute burst clear on the left and coolly tucked a left-foot shot under Ruddy to bring it back to 4-3, but in trying to get the ball back out of the net, Fryatt appeared to manhandle then kick City defender Barnett, and referee Walton sent him off.

With 10 minutes left, defender Steven Smith was handed his debut with Hoolahan perhaps surprisingly withdrawn.

Drury almost had a second when Steven Smith set him up for a low drive that Ikeme was grateful to hold on to.
