Loan players from Arsenal. If you are incredibly lucky you can get Bendtner or Vela as I have from experience; but other players there will suffice.
I think at a lower league team you are going to need big and powerful strikers like Adebayor who can guarantee a run of goals. So Spanish strikes and other strikes who are skillful player are not reliable.
Lacina Traore, 19 = £2.1m
would be my buy or:
Boakye, 17 = 1.8m
Cedric Bakambu, 19 = 1.8m
Cheik Sadibou Gueye & Marko Livaja were availanle for free but you are in January.
Three guys who may give you success who are also worth scouting for cheap prices are:
Vitaliy Balashov, 19 = £450,000
Marko Maletic, 16 = £350,000
Jelle Vossen,21 = £970,000
if you want to carry on Birmingham's likening for Scottish players or just want to have a British player
Leigh Griffiths, 19 = £600,000 would be my pick
