I doubt Bremer would accept a rotational role. He has his pick of CL clubs to join and become starter there.Swap deal would be ideal, I'm sure we'd chip in some extra cash, which is fine.
We could then also recruit Bremer for rotation with Dier.
Similarly, I don't think Pau Torres would be interested to join as bench player. Pau Torres may have the potential to eventually be better, but right now Bremer is better player. I think it's unrealistic to sign both. Pau Torres link sounds like the last option for us, while Villarreal trying to negotiate a cheaper deal for Lo Celso. They did something similar with Foyth last summer.
