A fit and firing Cristiano Ronaldo is "really happy" now his knee problem is behind him, according to Juventus boss Maurizio Sarri.
Portugal international Ronaldo started 2020 with a bang on Monday as he netted a hat-trick in the 4-0 win over Cagliari to take his tally to eight goals in his past five Serie A appearances.
The 34-year-old appears to have rediscovered his mojo having gone three games without scoring at the start of November, when he was twice substituted by Sarri as he battled a minor knee problem.
