Rangers have signed Rapid Vienna striker Nikica Jelavic for £4m. The 24-year-old Croatia international told Rangers' official website: "I know Dado [Prso] was a huge favourite of the Rangers fans and if I come even close to him then it will be good. "I want to try to copy what Dado Prso achieved here. "I spoke to Dado and he told me, 'look if you have a chance to go to Rangers it is something unbelievable and you must go'. "I am glad this whole saga with me, Rapid and Rangers is over and I have signed a four-year contract. "Lots of things have happened in the last month or so regarding this transfer but I don't want to think about that now. I only want to concentrate on my future with Rangers."
