If you 're making questions like a LV3 manager, I 'm answering to you like that
But you must be at least LV25 manager so you should know few more things.
A good TE manager is not the one who's buying young players, farming greens and pump their whites.
It's the one who knows how the game engine works (now, last month, before a year or two), understand the reactions of the game and some times can predict or avoid "troll" circumstances.
So, it is known that the game engine gives you a "bad day" in the first leg of a Cup round but can win or even dominate easily in the 2nd leg.
This happening usually in the first or 2nd round.
Another troll result is happening when facing the 3rd, the weaker team of CL groups.
