Why can't I score goals?

[michaelberry]

Sold Papiss Cisse at the end of my first season on my Newcastle save and bought both Lacina Traore (Anzi) and Seydou Doumbia (CSKA) and neither of them can score. I have Doumbia playing as a poacher on attack and Traore as a target man on attack. Incredibly annoying. Any help would be great
