I didn't say he was a solution.
I'd consider both Berge and Ugarte as stop-gap signings, with the club probably having a long-term target in mind who's significantly better than both of them.
I also think Berge is a better fit for what we want, despite being cheaper. I'd rather get the guy for 20-25m on reasonable wages to do a decent job for a season, instead of getting another not completely, arguably even less ideal player in Ugarte for 50m and at least 120k/week wages who will also have to be upgraded on and replaced relatively soon.
Ugarte will be harder to sell, and will make it harder for us to get someone like an Adam Wharton or whoever we want to address the midfield with. His peak value will almost certainly never rise to a higher number than the 50m we would be paying for him this summer.
With Berge, it depends on how much we would be getting him for, but if he does well at United for a few seasons, we can sell for a profit / not make a loss, or we can have a good squad player on reasonable wages that's satisfied with limited game time. With Ugarte, like I said, it's 99% that no one will ever pay 50m for him.
P.S: Darwin is far from being "piss poor".
