Khalid ibn al-walid, Winfield Scott (if you dont consider American a European), Yi Sun Sin (although he was an admiral), Han Xin, Tamerlame, etc... Well if you dont want to consider European generasl the greatest, then who? I dont want to be ignorant of other regional leaders, indeed I dont know as much about them as the European ones, but I still have yet to meet many that could even be said to be greater than Fredrick the Great (or even his equal).
