This news is just a sweetener for the transfer market. Casemiro will not be interested in joining Manchester United if the conditions of the club you mention are still as they are today. Manchester United in my opinion is a club that has no goal to achieve as long as it is managed by the Glazer family. They only have a goal around the income that will be obtained. Casemiro is a great player. It would be a shame if he joined.
It is just a rumor, don't take it too seriously.
We all know that Casemiro has no reason to leave Real Madrid. He feels happy to be one of the main midfielders of the best club in the world. It is impossible to expect him moving to Man United. Man United is no longer a big club, it has a very complicated problem after Ferguson retires. Casemiro must feel afraid to join Man United even if they offer him a big salary. He may ruin his career if he joins Man United. The situation of Ronaldo in Man United is the perfect example of this. So, as far as Casemiro is expected to stay in Real Madrid or move to a better club, he seems not interested to join Man United.
