We wondered whether there would be more fun after the break, and Leicester delivered. Maddison and Vardy each scored a goal to take control, with Perez coming off the bench to score a magnificent double after Ward-Prowse had halved the deficit.
The Foxes had a terrific finale to a mainly disappointing season, while Southampton has gone six games without winning.
LEICESTER CITY (4-3-3): Kasper Schmeichel; James Justin, Jonny Evans, Wesley Fofana, Timothy Castagne; Kiernan Dewsbury-Hall; Nampalys Mendy, Youri Tielemans; James Maddison, Jamie Vardy, Harvey Barnes.
SOUTHAMPTON (5-4-1): Alex McCarthy; Kyle Walker-Peters, Mohammed Salisu, Jack Stephens, Lyanco, Nathan Redmond; Stuart Armstrong, Oriol Romeu, James Ward-Prowse, Mohamed Elyounoussi; Adam Armstrong.
GOAAAAAL! Maddison gives Leicester a 1-0 lead! That is dreadful from Southampton! Lyanco heads a long ball directly up in the air and then doesn’t get enough on his second header as he looks to divert it back to McCarthy. Vardy pokes the loose ball straight at the goalkeeper, but Maddison is on hand to tap home the rebound.
GOOOOAAAAL! It’s 2-0 to Leicester, and that should be that! Barnes scampers towards halfway before releasing Vardy with a well-timed ball down the left. The Foxes striker cuts inside a Southampton defender before finishing coolly past McCarthy at his near post as he grabs his 15th league goal of the season.
Goal! Ward-Prowse puts Southampton back in the game as he rifles the penalty into the bottom-left corner! Schmeichel had no chance.
GOOOAAAAL! 3-1 Leicester is undoubtedly game over now! Maddison receives the ball on the left wing before opening his body and picking out Perez with a brilliant cross to the far post. The substitute does well to get over the ball and sends a low volley past McCarthy to restore the hosts’ two-goal cushion!
GOOOAAAL! Perez has his second goal, and Leicester have their fourth! It’s 4-1 to the hosts as Pereira is played in behind on the Foxes’ right, and he cuts back for the substitute to hammer into the roof of the net to make the points safe!
So, what’s next?
Leicester ends the season in eighth place, overtaking the Wolves after Liverpool’s 3-1 comeback win over Bruno Lage’s men.
However, it will be a long three months without a league game for 15th-placed Southampton, who end the campaign in dire form after being on the wrong end of a rout at the King Power Stadium.
