Can I beat him?

I was rekt 7:0

Do not worry too much about that. You'll always find people to tell you that you should do this or that and win. With such a difference in terms of quality, you only had to rely on a miracle. Sometimes miracles happen. Most of the times, they do not. I have never ever lost to a side like yours when I had such a quality advantage. And I won once when being in the other situation butmy opponent had probably dropped his team a while ago and his players were not properly prepared. With an active manager, let us be serious, you just had no chance to win, whatever your tactic is.
