If Aubameyang isn't a crucial player for Chelsea, Chelsea management won't force them to sign Aubameyang on the last day of the transfer window. If you followed the issue on Chelsea squad, you must know that Chelsea was looking for a strong CF to be the replacement for Lukaku. Chelsea needs a pure CF to score more goals, Aubameyang is a perfect player to solve the crisis in Chelsea attacking line. Anyway, Havertz isn't a pure CF, so he has nothing to do with Aubameyang's position. Don't you understand that Havertz is an attacking midfielder? 
Honestly, I think Aubameyang is a good player on the pitch. Maybe off pitch he has had some issues. I am quite sure he will deliver for Chelsea on the pitch. He is the kind of guy who can fit anywhere, but sort of unlucky not to settle. Look at what happened in Barca last season. He literally saved them from the embarrassment, only for them to push him out.Aubameyang is a football player who is very successful in his own region on the field. We have to accept this. He went to Barcelona last year and took Barça off the rope in many matches. Frankly, I thought that he would not be successful when he went to Barça, but he made a show in Barça. I am confident that he will be successful at Chelsea as well.
For me it was a very bad move between Barcelona and Aubameyang and this shows me that Barcelona does not have much gratitude towards the player, because it is as you say, when no one wanted to stand up for this team there he was, I don't know, but after Seeing Lewa arrive And after building a team with very great strengths, which even incurred very large debts, and taking him out does not seem to me, however, Chelsea will take advantage of all his talent, for me he will shine much more, and I would like to see a match between Barcelona and Chelsea and if Aubameyang scores a goal it will be something historic and well, for those things they deserve it, they shouldn't have sold it.
What Ronaldo wants is not money, he already has everything when it comes to money. But he still insisted on wanting to play in the Champions League. For a Ronaldo, money is not everything but his prestige on the football stage must continue to shine. That is evidenced by his ambition that offers to every club that plays in the Champions League to be able to take it. Ronaldo doesn't want his reputation to be pursued by Messi, because currently, Messi is still productive and better than Ronaldo in his old age. Therefore Ronaldo was determined not to be left behind.
Messi is in a different league and club competition. we can't compare the two for this.yes, Ronaldo does not consider money for him. there was even a rumor regarding a lower salary for a club willing to take him.
Ronaldo had stayed at Manchester United last season with poor form from the team. they didn't play in the Champions League this season. but Ronaldo's ambitious attitude seems to make many clubs not too interested in him.
although I believe Ronaldo can still perform quite well, but not sure that he can compete with the young players at this time.
I really do not think that CR7 can recover now, for me the only hope that CR7 has is for the World Cup in Qatar, for me it is the only option to raise my head, we all see it from the fubbtolist point of view, and the chaotic +he is not being haunted like this, I think CR7 has been like this since his baby died, it affected him a lot, and that is something that he is showing on the courts, no team wants to have him, he also rejected one that they offered $242 million just because he doesn't want to play in the Arab league, sometimes there are many things that CR7 demonstrates that they teach us all, but there is a possibility, which I read, I don't know if it's true, but it may be the only way that he bug plays, and it is that Spoting Lisboa asks for it and then if he can play in the UCL, but it's all mere speculation, I don't know how real this is.
but there are those who fully trust CR7 and it is their selection:
