In my opinion/experience corner spcialists are very effective. My one v one striker is my top scorer, defensive wall with the combination of pk stopper(goalie) using high pitch press and hard tackle has been quite effective. I have yet to see real results from my mc playmaker( still early though). One thing though is an mc shadow striker seems highly sout after in the transfer market. Still can't get my hands on one though. My thought is that these things also depend on your tactics. Would love to get an aerial header as well. Good topic
