I don’t think any manager should have ultimate control over transfers, but they should have a large say since they are the ones blamed and inevitably sacked if it all goes wrong. There is definitely a balance to be had between to the two.
Agree about Klopp and Pep, but I also think they would have struggled to achieve what Howe has up to this season. That’s how remarkable it has been under Howe and why he has to at least be given next season.
