Brendan Rodgers saluted "world-class" Jamie Vardy after he sealed Leicester's late 1-0 win as spluttering Arsenal crashed to a third defeat in their last four Premier League games.
Vardy was only fit enough for the bench after a calf injury, but Foxes manager Rodgers sent the striker on with 30 minutes left. Vardy responded with his sixth goal of the season.
The 33-year-old has made a habit of tormenting Arsenal and has now scored 11 goals in 12 Premier League games against them.
"Our plan was always to bring Jamie Vardy into the game and he can stretch it," said Rodgers.
"He makes the big contributions in the big games," he added after Leicester's first win at Arsenal since 1973.
"That shows you the level he is at and he is a world-class player. I'm lucky to have him."
Leicester climbed to fourth after ending a run of two successive league defeats.
"We deserved it, we played against a really good side and have players who can run in behind," Rodgers said.
"To keep a clean sheet and play with the quality and calmness was good."
Arsenal are languishing in 10th after a second consecutive league loss following their 1-0 defeat at Manchester City last weekend.
