No. No moaning on your part.
I don't worry much for the squad depth "issue" either. It was the same at Dortmund. Klopp didn't believe in the general "two first team players for every position". He believes in people that can play several positions and having a few players that can play everywhere. He had
Großkreutz at Dortmund. Milner at Liverpool.
It's no secret that Klopp believe that by keeping 2-3 spots open for academy players, there is a much better chance for them to evolve and become first team players. He had a program to educate and promote youth that he set in place in Dortmund and he's done the same thing in Liverpool.
Yes there are risks. But there are many upsides. From a business perspective, he gets a shit load of money for the youth players that doesn't cut it. Second, players like Alexander Arnold and Götze, would never, have been given the chance or confidence of they had played for Mourinho (just as an example).
It can swing both ways. Sometimes it's awesome, sometimes it sucks. It has worked for him, so I don't see how people can be so black and white about it.
