Im in my first season with Real Madrid and its January, I only have 2 strikers Benzema and Higuain ive got a budget of 7M and cant think of a back up striker?
Raul is still a good back up. for 7m your not going to get many good choices, try to get Romelo Lukaku, wonderful prospect and he can play pretty well for a 16/17 year old.
muniain looks very bleak. hard to get him for just 7m unless you pull the right strings and with luck.
Try loaning with the 7m as a loan fee(also pay 100% of the salary since you are real madrid) Soldado/Huntelaar/Tevez, all three players are quite consistent and will deliver goals if played right.
Benzema is inconsistent as **** in the game. If i were you id play Raul up front with Higuain. He'll probably last for another 2 seasons.
You can sell Mamadou Diarra for a good amount to increase your budget. You'd probably have 7m+8m and you can buy Neymar, Macheda, Traore or Lukaku as replacement.
Daniel Aquino is available for £3 million is a young spanish player who can play upfront and on left wing. Or you can pay £7 million upfront and £20 million over 48 months and buy Dzeko
