Of course you just conveniently ignored the fact it was Zinchenko who worked hard to produce the first goal. You can't be serious nitpicking his errors in his overall excellent performance in that match. Who started the next match again? In case you don't know he was Fotmob's MOTM in that match. I honestly trust their logical and meaningful rating system unlike the garbage take of Whoscored, bias pundits on TV and paper or an amateur in a fan forum.
I watched the whole match live & gave an honest personal assessment. As I said, Arsenal bossed it for the first 30-35 mins & yes Zinchenko's pass led to Arsenal's opener. Arsenal were all over Palace like a rash & were bossing the match with Zinchenko being as impressive as the rest of the Arsenal starting 11.
However, as stated around the half hour mark, Zinchenko was caught upfield when a ball was played into the space he vacated, & that's when the penny dropped for Palace. They began to overload their right (Arsenal's left) & recovered to finish the half even in terms of control.
In the second half it was all Palace & it was evident Zinchenko's lack of pace was being targeted as most of Palace's attacks came from their right. This is something City became familiar with at the highest level during his time here, hence Zin never being first choice LB at a club who only had one LB who was perpetually injured.
Up to 70-75 mins of the second half there was only Palace in it, until Arteta pulled Zinchenko for Tierney which completely turned the second half tide in Arsenal's favour. Coincidence? Tierney's extra pace nullified Palace's main attacking tactic & that was it for them.
So much so that after regaining the initiative, Arsenal scored their second to put the match beyond Palace & comfortably saw the game out.
Did you even watch the match, or just read online blog reports?
Most City fans agree that Zinchenko is a very talented pro, but how many times has he been found wanting at the very highest levels where the smallest deficiencies are amplified? Why did Pep prefer a right back playing left back instead of Zinchenko?
Why were we desperately trying go get Walker fit to face Real away & why was Cancelo played at LB instead of Zinchenko? Why did the momentum of the match swing when Walker came off injured? Zinchenko replaced Walker & Cancelo moved to RB. Which side did the majority of Real's attacks come from which led to their two late goals?
It's early mate & you've probably woken up a bit grumpy for whatever reason. I'd suggest you reflect on Zinchenko's career at City & why we were comfortable in allowing him to leave. I'd also suggest you go watch the full Palace v Arsenal game & not solely rely on blog reports & MoTD highlights to try & form an accurate opinion... :-\
