Not sure about Edman. He did a good job as one of Arnesen's numerous signings, when we more or less rebuilt the squad in one summer (didn't we have about 8 debutants that first match??).
But after his head injury, I didn't feel he was ever quite as good. One incredible goal against Liverpool, but didn't create that much, and a little dodgy at the back.
I reckon YPL is an improvement. I also think BAE is quite promising for the long term.
