Playing Stronger Opponent?

Hi, I've just started playing Top Eleven, and I'm currently in Level 2.

In my cup this season, I've made it into the quarter-finals, where I have to play the strongest team in the cup :(
He has 23.5 stars, compared to my 19.0. In my away match against him I lost 3-1. So I was wondering if anyone would have anything that might help me to beat him, or just help in general about playing strong opponents. Any help would be much appreciated.

Also, two more points:
-He is playing his formation as 4-4-2, so any strong formations against this would also be appreciated.
-Would it be worth paying the two tokens it costs to change the match time to a time which I could attend?

Thanks in advance for any help :)
