Ronaldo came and Juventus collapsed. It was not Ronaldo who brought down Juventus, but Juventus dismantled its own dynasty system in order to cater to Ronaldo.

1. Before Cristiano Ronaldo came (2011–2018): Juventus can be called the "absolute hegemon of Italy" and is a mature, stable and strong-core system team.

Serie A: 8 consecutive championships

Coppa Italia: 4 consecutive championships

Almost ranked first in regular season points, goals conceded, and goal difference

Stable lineup: Chiellini, Bonucci, Buffon, Marchisio, Pjanic, Mandzukic

Continuous coaching system: Conte → Allegri

Stable Champions League results:

2015 Runner-up

2017 Runner-up

2. After Cristiano Ronaldo came (2018–2021): Juventus’ performance fell off a cliff

2018–19 (Cristiano Ronaldo’s first year): Although Cristiano Ronaldo contributed, the team began to decline as a whole

❌ The Italian Cup lost the championship → the consecutive championships ended

✔ Serie A champion (but points dropped and dominance declined significantly)

❌ The Champions League was upset by Ajax

2019–20 (Cristiano Ronaldo's second year): One of the most "struggling" champions in Juventus history, the Juventus dynasty is crumbling.

❌ Continue to lose the Coppa Italia

✔ Won the Serie A title (but it is very difficult to win)

❌ Eliminated from the Champions League by Lyon

2020–21 (Cristiano Ronaldo’s third year): The team has officially fallen to the level of the dynasty.

❌ Lost the Serie A title (9 consecutive championships ended by Inter Milan)

❌ Almost fell out of the top four → Finally relied on the help of others to enter the Champions League

❌ The Champions League was eliminated by Porto

3. The reason for the decline cannot be blamed on Ronaldo, but that Juventus regarded Ronaldo as a "life-saving medicine", which ended up tearing apart the originally stable system.

3.1. With Ronaldo here, Juventus' offense "must revolve around him". Originally, Juventus was based on overall football + team defense + midfield control. But after Ronaldo arrived, the tactical focus shifted to "feeding Ronaldo the ball." Mandzukic's position was squeezed out, the midfield control was significantly reduced, the roles of Pjanic and Dybala were weakened, and the team became non-systemic and non-integrated, with only "Cronalo scoring goals" left.

3.2. The midfield is weakening at a cliff (core issue): The real reason for Juventus's decline lies in the midfield. Pjanic is aging, Khedira's condition is declining, and he spent huge sums of money to buy RAMSEY, Rabiot, Arthur... The result is that they all failed. There is no organization, no advancement, and no continuous pressure. As a result, the frontcourt players rely entirely on individuals. It is unrealistic for you to let the 35-year-old Ronaldo be responsible for the team's advancement and goals.

3.3. The coaching system was destroyed: Juventus changed three coaches in three years during the Ronaldo era: Allegri, Sarri, and Pirlo. The system was constantly rebuilt, and the team became more and more chaotic.

4. The most critical fact: Cristiano Ronaldo’s statistics are top-notch, but Juventus’ system collapsed

✔ Cristiano Ronaldo played 134 games at Juventus → 101 goals

✔ Serie A Golden Boot

✔ Serie A scoring record for 11 consecutive games

But:

❌ The team's dominance declined

❌ The domestic cup was lost for two years

❌ The consecutive Serie A championships were terminated

❌ The Champions League was eliminated early in all three years

❌ In the end, it was almost impossible to keep the top four

Ronaldo is very strong, but Juventus itself needs "system players" more than a super terminator. Ronaldo is not the reason for Juventus' decline, but his arrival has accelerated the fact that the Juventus dynasty is old, and the team has dismantled the final system in order to cater to a super scorer.
