One positive for the Foxes was the return of winger Riyad Mahrez, who played just under half an hour in place of Fousseni Diabate. He loves his team-mates, and that's important.
Pep Guardiola's side romped to a 5-1 win against Leicester at the Etihad Stadium on Saturday with Aguero scoring four times in the second half, but De Bruyne took numerous plaudits for pulling the strings in midfield and setting up City's first three goals.
"I'm really happy personally because the goals are helping the team to win and obviously that's very important", Aguero said.
Leicester have not won a Premier League game in his absence and travel to the Etihad to face City on Saturday.
The 29-year-old Algerian received a good reception from both sets of fans - particularly the home supporters - when he replaced Fousseni Diabate but the pain must have come flooding back as Sergio Aguero scored four.
Leicester sources stress that keeping such information confidential is to adhere to employment law but the uncertainty is casting a shadow over the club. We expect the game to end in a draw considering City's defence will have a makeshift left-back and a new signing in Laporte who will need some time to acclimatise to the Premier League. We have had three training sessions and we are ready to come back now.
'He will come back with a good attitude and good level.
Puel said: "I can understand all this speculation about the situation but I cannot comment on this, it is not right".
"Those goals remain the same today and in the future and when I am asked to be a part of the Leicester team, rest assured I will continue to give my all".
"Hopefully we can keep doing the same way".
In the process he joined Harry Kane, Thierry Henry and Alan Shearer as the fourth player to score more than 20 goals in four successive Premier League seasons. "It is important to move together with good solidarity and understanding together".
Mahrez's worldwide coach Rabah Madjer said the player "deserves better than Leicester", but former England striker Chris Sutton was critical of the player's reaction to his move collapsing.
