“We want to go as high as possible in the league and the reaction today after the goal we conceded was really good,” the French striker told BT Sport.
“We know it’s really important now, we have March April and May to finish well. Comeback wins in two successive games will be a massive confidence boost.”
Leicester took a sixth-minute lead at King Power stadium as Youri Tielemans robbed two Arsenal players of the ball on the right flank and cut inside the area before he fired a low shot into the far corner.
The Gunners equalised in the 39th when Luiz headed a Willian cross into the bottom right corner and Lacazette turned the tide in first-half stoppage time as he drilled in a penalty after a VAR check showed Wilfred Ndidi had handled the ball in the area.
Poor defending cost Leicester again in the 52nd minute as they allowed the visitors to break through the middle before Willian slipped the ball to Pepe and the Ivorian forward tucked it into an empty net from two metres.
Arsenal held on comfortably in the closing stages and missed chances to win by a bigger margin as Kieran Tierney volleyed just wide from 20 metres and Pierre-Emerick Aubameyang came close with a fizzing low shot.
Kelechi Iheanacho summed up Leicester’s afternoon in the last minute of stoppage time when he blazed the ball over the bar with the goal at his mercy.
Fulham and Palace draw
Meanwhile, Fulham moved to within three points of safety after Palace goalkeeper Vicente Guaita reacted quickly to keep out a header from Fulham’s Josh Maja.
Centreback Joachim Andersen threatened the goal at both ends, forcing a save from his own goalkeeper with a misplaced clearance attempt, and heading wide at a corner soon after. He also had a shot blocked by Palace defender Gary Cahill later on in a game where set pieces often proved the most effective way to create chances.
Fulham’s Ademola Lookman and Maja sent shots wide late in the game as Fulham pushed for what could have been their first back-to-back wins since returning to the Premier League this season. Fulham has conceded one goal in their last five league games.
Roy Hodgson’s team has now lost three of their last four league games without scoring, with the exception being a 2-1 win over Brighton on Monday.
