Change your formation, optimizing for defensive solidity.

Started to struggle last season after playing a 3-2-1-3-1 for 6 seasons. Switched to a 4-3-3 low pressing and damn, man.

Lost 4 games and drew 2 of 13 in the league, and obtained only 7 of 18 points in the CL in the first half of the season. In the second half after the tactical changes, won 12, drawing only 1, to lose the league by just 2 points. Won the SL and only got dumped out in the cup SF on away goals rule.

It happens in real life too. The other sides "figure you out".
