Without a doubt Darwin Quintero for your striker, i think i got him for £3.5m and he was topscorer on the way to finishing 4th with Wolves. 32 in 36 league. 45 in 42 overall.
Midfielder Ruben Yttergard Jenssen. Leading assists in the first season too, and cheap £3m. As for LB Piere Wome, free and reliable.
