Leandro Damiao (if 2nd season onwards with instalments) - this one should be your number one target.
Falcao (transfer listed second season usually).
There is no other choice.
He has been immense for me, had him at West Ham, he guided me to Prem glory, then got Man Utd job and bought him.
52 goals in 43 games first season and 28 in 16 games so far.
