Don't buy anyone is a solid option. Last year when we had the striker crisis (around the same time as this year) we brought Paolucci, he started one match and came as a sub on another and was of no use at all, except that Moggi and some other made fun of the transfer and hurt our image a lot.
Amauri and Del Piero are available, Iaquinta will be back in a week or so and Toni will be available too after 3-4 rounds. I doubt that FF will give us much more, or anything more than the primavera strikers so I see no use of paying 1-2 million and humiliate ourselves this way.
