After the toughest of baptisms when they took on the might of Manchester City, Chris Hughton's side were taught another harsh lesson by the 2016 champions.
It was as easy as any win comes in the Premier League and carefree Mahrez led the charge as he taunted Brighton, shaking off continued transfer speculation. "It was hard to break them down, but it was a good performance". Brighton goalkeeper Mathew Ryan managed to get a hand to it, only for the rebound to fall straight to Okazaki, who calmly slotted home to give Leicester the lead in the opening minute.
After Leicester had dominated the first quarter of the game, there was at least some encouragement for Hughton as Glenn Murray was ruled offside as he tucked away an angled shot and then they had appeals for a penalty waved away by Lee Probert after a fiercely-struck shot from Jamie Murphy appeared to hit Morgan on the arm as he charged it down. "It's really just a second opinion".
Dunk's first Premier League campaign began in inauspicious style with an own goal in last weekend's 2-0 defeat to Manchester City, but Hughton is confident his player has the potential to make the step up and perhaps progress to the national team.
Jamie Vardy already has two goals to his name and whilst Mahrez remains on Leicester's books, the home team have plenty of creativity and skill to beat Brighton.
A 10-man West Ham conceded a stoppage-time penalty after fighting back from 2-0 down at Southampton to lose 3-2. Anthony Knockaert will be hoping to make an appearance against his former side.
Vardy almost had another chance to double the lead four minutes later after Okazaki managed to win the ball back in the Brighton half, squaring it to Wilfred Ndidi who played an excellent through-ball.
