Referee Graham Scott reached into his pocket but showed Kompany just a yellow, which the home fans inside the King Power Stadium were left angered by.
Speaking to Sky Sports News at full time, Puel questioned the referee's decision to let Kompany remain on the pitch and claimed that it may have been a different game had a red been awarded. "Yes, of course [the game was defined by small margins] because there are so many events in this game".
Vincent Kompany and Benjamin Mendy are joined on the sidelines by the suspended Nicolas Otamendi. "We continue with our good rhythm in terms of points and the way we play". "That decision changed the face of the game". We'll have a go at them and we'll try and get something from them.
"We need many things".
"I am really impressed because after more than two months injured and (having had) one game at worldwide against Gibraltar and to play at that level shows how strong he is in his mind", said Guardiola.

It was not easy after three minutes 2-0 down, especially because Leicester is such a complicated team for the way they play with the runs in behind with Vardy, [Shinji] Okazaki who is a fighter, and now Kelechi [Iheanacho].
