Former Real Madrid and Brazil player Savio says Vinicius Junior is experiencing the most serious slump of his career.
The 26-year-old winger has made an underwhelming start to the current campaign and has faced criticism from the public over his performances.
Vinicius has scored one goal and provided three assists in eight appearances for Jose Mourinho’s side in all competitions.
Savio’s comments come as the Brazil international continues to attract scrutiny over his form at the beginning of the season.
