Thanks for you compliment, mate.
Please see your inbox, I sent you a message.
Sometimes, you need to change, sometimes, you don't. I don't know for sure yet when you need and when don't. But Counter seems to work better. However, when it comes to the second season, the M.U players are extremely familiar with the tactics, I defeated M.C Etihad with 4-2 and didn't need to change to Counter
1 of my friends told me that it is not until 2020 in the game that the tactics will be defeated by AI. I'm not sure about this
