Ronaldo joined Juventus in a £88million move from Real Madrid in the summer of 2018 to great fanfare and expectation.
Here was a superstar who was meant to propel Juve back to the summit of European football by guiding them to Champions League glory for the first time since 1996.
The Portuguese powerhouse arrived in Turin off the back of inspiring Real Madrid to an unprecedented third-successive Champions League. It was his fourth in five years at the Spanish giants and Juve were hoping this form would correlate upon joining them.
During that final 2017-18 campaign at Real, he scored 15 goals in the Champions League to finish as the competition's top scorer - five more than Liverpool trio Mohamed Salah, Roberto Firmino and Sadio Mane (all 10).
Juventus saw the Ronaldo effect that season at close-hand as he ended their participation in the tournament at the quarter-final stage.
The iconic No 7 scored twice in Turin as Real won 3-0 at Juventus in the first leg. Massimiliano Allegri's side were winning 3-0 in the reverse encounter, and looked set to force extra-time, before a 90+8-minute stoppage-time penalty from Ronaldo saw Real progress 4-3 on aggregate in the most dramatic of finishes.
Fast-forward those three years now and that unparalleled success at Real has been met with unparalleled disappointment at Juventus.
In truth, and rather surprisingly, Juve have gone backwards in Europe since Ronaldo has joined them.
