I would suggest that you tweak the FC's instructions to get the best out of him. Adjusting his instructions that plays to his strengths would help you reach that goal, eg(my theory), unless the FCs long shot ability for long shots are 14 and above, I would set that instruction to rarely. Those with 14 and above would then to set to mix, never often.(strikers are meant to take long shots all the time, imo).
Among all, if you at the start of the game and/or using a new tactic set, then give some time for the strikers(all players for that matter) time to adapt to their respective roles.
