Magath hated Jones and Jones is just Jenas with a German passport....that's a no go. Plus they have Dejegah as a running CM.
Ochs is already purchased. Hutton is not a consideration
Wilson, Kranky and Pavs would best suit their system. But they already have players in two of those positions.
For DM, they have Josue, who Magath installed as captain when they won the title. Doubt he would spend 12 million to replace him with Wilson (Levy won't lose money on him).
Pavs...maybe, but they already have Helmes and Mandzudik...good paring. Better than any we have. It would depend on whether he's ready to let Grafite go.
So that leave Krajcar. I think they might be in for him. But they won't spend too much when they can just pop over to Croatia and get the next Kranjcar for cheap.
Kranjcar is actually being linked with Wolfsburg via Bild (as a Diego replacement).
For their striker needs, don't forget that they also signed Lakic (although that was prior to Magath taking charge).
