Okay let me break this down. I said it in the newbie forum and I'll say it again here. Ronaldo was either carrying an genuine knee injury, or he either clearly doesn't give a shit anymore or his legs are completely officially gone. He didn't press and back track not once in the 15 mins he was on, he made a mess of simple through balls and on the break on the counter before the final whistle, he had all the time in the world to release the pass to Bruno and instead ended up dwelling on the ball until he gave the ball away.
Losing that foot race to that generic defender was a sad sight to see and will hopefully drill home the message that he isn't cut out for this anymore. I have an inkling that Ten Hag told him when he first met him that he wasn't going to be a guaranteed a first team starter which triggered him to get his agent to angle a move away since psychologically in his mind he believed the notion that he was the catalysis from saving united from relegation last season and still one of the best bred forwards in the world. All the adulation from delirious fanboys of his, through the stat padding went to his head like a shot of heroin.
Now it's obvious no top teams competing in the CL he has humbled himself and reality has finally hit home that he is not top dog any longer which has prevented him from creating a list Hollywood scenes, leaving the stadium early with his boy toy Dalot to create headlines,, he's now left to seriously consider the prospect of joining the likes of Napoli or Sporting Honestly if he continues to put in performances like that he'd be better off joining a club in a less intense league because if he stays here, he'll will get exposed the same way Antony Joshua is getting exposed for being stiff.
