As has been said 100 times already, tactic is insane.
I took over Cagliari, a bad Italian side, but one with players that fit the tactic fairly well. Only signing first season were loan players as backups. Finished 2nd in the league with 83 points, and won Italian Cup.
Second season, signed Lautaro Martinez, Jorge (Tenerife), Predrag Rajkovic, and Leo Pele, who didn't play a minute due to non-EU roster rules. Sold Diego Farias, and had a bunch of minor departures. Once again, finished second in the league, on 81 points, lost in Italian cup final, but in a total shocker, won the Champion's League after beating Bayern, Atletico, Man City, and PSG. In the final against PSG, my total wage budget was 670k$usd/week, whereas Neymar alone makes 825. Need to decide if I'll stick with Cagliari to go for the Scudetto, or if I'll take a big time job.
