It wasn’t. We concede more goals, score fewer goals, win fewer points, create fewer chances, concede more chances and play less direct fotball with him than we did before he arrived. These are statistical facts. It’s also valid for the small amount of time without him on the pitch after his arrival.
He doesn’t make the players around him better, quite the contrary. When everyone one else gets 5% extra workload and we don’t win the ball when our opponents are out of balance as often, that changes the dynamics of our game completely. Ronaldo plays for himself and no one else. He‘s there to score important goals every now and then, but goes completely missing when we don’t have the ball or on cold nights in, let’s say, Newcastle when an extra shift is needed. Instead of being an inspiring leader on the pitch, he sucks the life out of you with his bodylanguage when things get tough.
He was one of the main factors for the Juve era’s end as well. Serie A went from being a one team league to a wide open one in 1,5 seasons with him at Juve.
He’s had an unbelievable career and a fantastic 10 year long peak where he took goalscoring to another level, but now his status is way bigger than the player he currently is, and that drags us down. it’s not possible to make a top team click with the current version of him in it, unless he suddenly changes his personality, attitude and workethics on the pitch, and I don’t think that’s going to happen.
