Just got mid Matthaus from mid icon pack. I have untradeable TOTS Gabriel at the stay back CDM position. To free up coins, I sold one of my CB, baby Campbell and put Matthaus at the CB position with 7 chemistry. After minute 1, I can keep playing TOTS Gabriel at CDM and Matthaus at CB position or I can switch them. Which way is better? Also which chem style should I used on Matthäus? Thanks for any suggestions!!!
