Ronaldo hasn’t scored more than 26 goals in La Liga since 2015-16. The days where he would put 50-60 goals a season are long gone.
The sample size for that is really only 2 seasons though if we're just taking into consideration his Madrid years. Even then, he never played more than 27-29 league games in those seasons with Madrid focusing more on the CL which inadvertently meant he mainly played the stronger teams whenever he featured in the league so didn't have the opportunity to stat pad. Here in Italy, he plays both weak and strong and the outcome is the same - barely any service.
With a far more creative midfield and better Fbs, there's no doubt his volume of goals would increase dramatically.
