It's a fair observation in so far as, yes he seems to be sticking with players he knows. I think "cop out" is unfair, I mean Mourinho at Chelsea simply brought over his Porto squad.
That's all very well, but how many of these players have improved since 2019 or since United signed them? The players Jose brought in had just won the champions league and the majority of them became Chelsea legends.
I tend to think Ten Hag was/is hoping the same would be true for the players that followed him. Because it's yet to come to fruition doesn't change the fact that it's a tried and tested method of building a good squad - go with familiar players.
