How to be successful in CL with a middle/lower club?

In the leauge I play a possession based tactic but I dont think it will work in CL so Im looking for a good counter tactic, I tried some variations myself but it didnt work any suggesions about how a counter attacking tactic should be?

What kind of formation do you use and what players do you have ?
