But that's not the usual outcome, is it?
You have to buy players that look to be able to fit in, and then give them time.
Origi is just Origi, and Minamino was bought just because he was cheap and had one good game against us in the CL. That's a weak foundation for a transfer decision imo. No wonder he is struggling to settle in.
From what I have heard, we take our time assessing players, we do not jump on the latest name, the transfer team check their history/personality etc to make sure they will fit in, so I doubt we signed him as he was cheap, he was a player we were interested in and who had a good release clause we could use, that is why we have been so successful in the transfer market over the last few years.
As other have said, he has come from a different league, moved to a new country with a new language in the midst of a pandemic where he has probably been in isolation on his own, with very little game time, so with all this, it is far too early to judge him.
