Dopo le partenze di Michael Lang (Basilea) e Amir Abrashi (Friburgo), il Grasshopper ha messo a segno un importante colpo anche in entrata. Le Cavallette hanno infatti ingaggiato lo svedese Kim Källström, in arrivo dallo Spartak Mosca.
Il centrocampista centrale in passato ha giocato per sei stagioni con il Lione (dal 2006 al 2012), con cui ha vinto due campionati e due Coppe di Francia. Il 32enne da diversi anni è pure uno dei pilastri della sua Nazionale. Con la maglia della selezione nordica ha collezionato 118 presenze, condite da 16 reti.
