I was also surprised by the Manchester United game against Omonia yesterday. They seem to be struggling even though they are only against a small team from Cyprus and they will almost lose if Marcus Rashford doesn't score a third goal. Ronaldo is still under-perform considering his age is also not young anymore.
Ronaldo can't play like he used to, but united is a team with more potential. With 2-3 transfer reinforcements, this team can come to a really good place. They especially need to fix the defense. I think they will try to solve some of this problem with kim min jae from napoli. If that happens, it could really work. A striker and a midfielder would be really good. They are conceding too many goals. If they don't find a solution for the defense, they will drop mentally after every goal they concede.
Ronaldo looks very frustrated with his performance. I see at this time the CR7 seems to be depressed so it is very difficult to restore the actual performance. But I'm sure if Erik Ten Haag gives Ronaldo minutes every week he will find his best form again. Ten Haag must also focus on his squad and not be consumed by issues that make him hesitate in making decisions and the former Ajax manager must also make use of experienced players like Casemiro and Varane.
Ten Hag is doing wierd moves for Man utd this season he bought some players and putted them on bench especially Casemiro that played every match for Real Madrid,so this move is really wierd from im to not put him from the start. While Ronaldo currently is in bad form and isnt used to not playing or playing only 45 minutes from the bench. He is a player that needs to either play 90 minutes or not play at all and how we all know his ego he is not satisfied with not playing at all.
