Svensson has coached half a season of relegation battle. Urs Fischer has done really well with one of the biggest underdogs of the league, but Spurs would be an entirely different beast. Terzic - as unproven as he still is - would actually be the most reasonable, because he has (eventually) succeeded in a high pressure scenario, he did well in the CL and he's won some silverware in the domestic cup.
Hütter, Rose and Marsch were the logical choices on the German market, but they have signed elsewhere now.
