If you look t the level of rivalry and supposed hatred between Sergio Ramos and Barcelona, and Lionel Messi in particular, I'm about the hostility in every match they played against each other which often leads to physical bruises of intentional gesture and always unremorseful about awful tackles that could cause a career threatening injury, you'd presume that Messi and Ramos would never have any respect for each let share a dressing and be highly professional about it as though they've never being on extreme opposing sides of heated rivalry.
There have been some speculations about how Sergio Ramos isn't being welcomed back well by Sevilla fans, I guess probably due to their history while he was at Real Madrid, but Sevilla as a club right now are in total disarray defensively since the beginning of the new season, If there any defender out there that his level of experience at all level could help them, even if it is mean to be just within the dressing room, Sergio Ramos by all means is one of such players.
That's the media and the fanbase that usually likes to make a lot out of the rivalry trying to paint Ramos/Messi as hateful of each ither. Not true, both are really professional and competitive, you see the same in some other sports, fighting or boxing, they look like they hate each other but in the end it is respect. If you don't respect your opponent you don't even try to tackle them
You see this in football teams who look down on others don't even try hard.
Anyway, it's not my club anymore and Sevilla is in flux, I am now more concerned how to defeat Bellingham and even how to deal with Atletico!!
