Onana's passing error made Casemiro commit a foul which resulted in a second yellow card for him which made Casemiro leave the field although the penalty did not become a gol because it was too wide but mistakes were made again by Manchester United players which made Icardi successfully punish them in this match.
This is obviously very good for you and the Galatasaray supporters but a little bad for Manchester United because in the first 2 matches Manchester United had to lose points with 2 defeats which made them the caretaker of group A without points.
Actually, three goals from Galatasaray is not totally mistake from Andre Onana, most weakness with left and right defender position how Galatasaray easily scoring goals last night. Despite his fatal mistake with wrong passing and make Casemiro have received second yellow card actually Manchester United defensive most weakness. Personally, I most excited with Manchester United forward Rasmus Højlund success made brave in this match and specially his second goals with brilliant dribbling start from in the middle field, but he was not luck with Manchester United have got bad result.
Seems Manchester United in terrible condition right now, they have loss 2 of 2 matches in Champion League and left points from current standings almost close the opportunity qualify from group stage.
It should be noted that what I said earlier was not referring to the 3 goals that occurred but the process when Onana's missed pass earned Casemiro a red card.
I know the other 2 goals were not Onana's fault but it was indeed a missed pass that cost qpqQqManchester United because with that Casemiro was sent off clearly Onana's fault.
Hojlund as a striker has been a little better especially for the Brace in this match but in the end with some mistakes that they have not been able to minimize still makes Manchester United slump.
There is stil a chance of 4 more matches in the Champions League but that opportunity must be tried to win against Copenhagen later. because if they don't get points back honestly I doubt they are still fighting for second place.
