The Manchester City boss guided his team to a 0-1 win and after the match he went over to speak to the Foxes midfielder in a passionate manner.
Kevin De Bruyne scored the only goal of the game as Leicester frustrated the visitors with a defensive setup until near the end of the game when they pushed for an equaliser.
Maddison told BT Sport what Guardiola said to him: “He was asking why we didn’t play like the last 15 minutes for the whole game.
“But he realises it’s not as easy as that.
“He’s a top manager with a top team and it’s always going to be tough.”
Brendan Rodgers set up his team in a compact 5-4-1 formation that restricted the Premier League champions to very few chances.
As Leicester searched for an equaliser Maddison played a key role in trying to create a chance.
He has been the club’s star player this season scoring six goals and assisting a further two in 11 matches in the Premier League.
Maddison has been knocking on the door for an England call-up with the World Cup just around the corner.
As for Guardiola, his side moved top of table but Arsenal are just a point behind and are yet to play this weekend.
This is not the first time the ex-Barcelona and Bayern Munich boss has confronted opposing players after matches for a chat.
He has previously gone up to Nathan Redmond when he was at Southampton telling him that his side should attack more.
