Because he doesn't think they are spending unlimited money.
If the Panamanian sovereign wealth fund and the Norweigian sovereign wealth fund bought Burnley and Fulham respectively and invested a few billion, knocking Liverpool down the table, do you think Klopp would be OK with it?
No, of course he wouldn't. Because he doesn't have anything against people from the Middle East, he has a problem with what he thinks is overinvestment from owners with essentially limitless wealth.
How do we know that's his problem? Because he literaly spent 20 fucking minutes explaining his problem on Friday in the press conference apparently none of you accusing him of xenophobia bothered to watch.
Like I said very clearly in my original comment, lots of criticism of City over the years has had an anti-arab or islamaphobic bent to it, but this categorically didn't and it's completely dishonest to pretend otherwise.
I know tensions are high after yesterday but I can't believe people are seriously arguing that Klopp is prejudiced against Arabs/the Middle East.
