City were beaten 3-1 by Lyon, after conceding two late Moussa Dembele goals.
Kevin De Bruyne had earlier cancelled out Maxwell Cornet’s opener.
The defeat meant City were eliminated from the quarter-final stage for a third season in a row, having emerged big favourites during the mini-tournament in Lisbon.
City defender, Aleksander Zinchenko, has now opened up on Guardiola’s reaction after the full-time whistle.
Zincheko told his partner, Vlada Seden, on her YouTube channel: “Guardiola didn’t even enter the locker room, and didn’t say a word after the match. What is there to say, if everything is clear?
“It’s a shame for David Silva and Claudio Bravo – they played their last match for Manchester City. We wanted to win first of all for them.”
