A former teammate of Cristiano Ronaldo, Leonardo Bonucci, has given a friendly warning to the other players at Manchester United about the soccer star. According to Bonucci, who plays for Ronaldo’s previous team of Juventus, having Ronaldo on the team resulted in the other players getting lazy and making easy mistakes. Bonucci says the team became so dependent on Ronaldo that with him the team was in danger of falling apart.

This Summer Ronaldo departed from the Turin-based club and returned to Manchester United. Since rejoining the Red Devils he has had one of the best seasons of his career so far, scoring five goals in just six matches. However, Bonucci says that’s not necessarily a good thing.

According to many, Bonucci included, Ronaldo’s three-year tenure at Juventus saw the team get progressively worse. The team’s first year with Ronaldo saw them have a fantastic season, ending with them taking home the Italian Supercup and the Serie A crown. However, the second year the team finished its first season in 7 years not taking home a second trophy. It was in Ronaldo’s final season that Juventus lost the Serie A, ending a winning streak for the team that had lasted for 10 years.

In spite of Bonucci’s claim, Juventus has struggled to perform without Ronaldo. The team has won only two of its six Serie A matches, losing to both Napoli and minnows Empoli.
