I have 4 strikers (bought one recently) and many a times I tend to use just 1 striker or a max of 2...
20 yr old one-on-one striker,31 q,market value = 2.23 m [he scored 11 goals and assisted 1 so far this season]
19 yr old striker,32 q,market value = 3.54 m [scored and assisted 3 so far,he rarely started this season]
