Most of the folks here making commentary about Ronaldo don't even watch any match. All they do is check results from livescores and stats. They forget so quickly that Ronaldo was Manchester United's top scorer last season. He was the 3rd top scorer in the EPL with 18 goals. He out scored younger Harry Kane and the likes
He saved Manchester United from many embarrassing situations, but now that he is not getting enough play time this season, people are so quick to judge negatively.
Also, many people forget that because of his epic with a possible transfer to another club for the sake of participating in the Champions League, Ronaldo did not take a full part in the pre-season training of the team and he needs some time to get into fighting physical shape. This is what Ten Hag insisted on in the first matches, when he explained why Ronaldo does not get full playing time. It was also clearly evident that Ronaldo was not as concentrated as before because of all these events. All this, coupled with a small playing time, also has its negative impact, because Cristiano is not used to being a substitute player who tries to use his chances in a short playing time. Summing up all the above, I would like to say that it is not worth burying a player's career and Ronaldo is able to regain his former condition at least this season and be at least at the level of the top strikers of the English Premier League.
