Talismanic Belgium pass master, Kevin De Bruyne, located Sterling with his trademark passes for the opener of the game. "Now it's important to move on together and prepare for the next game".
Puel had said on Thursday that Mahrez would not play at the Etihad Stadium but named him on the bench and brought him on with almost half an hour to play, although it was to no avail as the Foxes were heavily beaten.
No player has provided more assists in Europe's top five leagues than Kevin De Bruyne since he made his Wolfsburg debut in 2012.

Aguero's four goals took his total for the campaign to 28 in all competitions and his overall City tally to 197.
The best first-half chance to make it two came when the midfielder found Sterling with a precise through ball, but the No 7's shot was blocked by Aleksandar Dragovic after he'd rounded Schmeichel.

If not for Leicester's haphazard defending in the second half, their attackers might have given City a run for their money.
After 25 minutes of patience and control, Aguero finally managed to bag his hat-trick, thanks mostly to a shocking piece of play by Kasper Schmeichel. Foxes striker Jamie Vardy burst away from De Bruyne's attempted tackle in midfield, before taking on £57m man Laporte. It looks all but guaranteed that the Cityzens will go on to be crowned champions, and they have undoubtedly been one of the best sides in Premier League history.More news: Trump's confidantes explain the confounding reason Trump won't fire John Kelly
