I agree with your first formation. Fast wingers and 2 classical strikers. Mandzukic for hold up play and headers and higuain to run into space. Not saying it gives us a great chance, but it gives us a chance. I honestly think the second leg being away helps us slightly. Like Atletico were dead in the semis last season because they were home the second leg. For us, if we have an amazing 2-0 start in this match, we are absolutely alive.
I personally like 4-3-1-2 but 4-3-3 or 4-3-2-1 is as good depends on the players..
against Real Madrid 4-3-3 or 4-3-2-1 with the 2 going wide and central is probably the best formation we can field against them
