I would rather want Benzema to stay rather than Higuain. I still think Benzema has a lot more to offer and plays well in big matches compared to Higuain. Pogba would be a great addition to the club. I agree with you about Modric. Really is a class player and has shown how talented he is. He should be part of Madrid's long terms plans.
Our first step needs to be getting rid off Kaka. He was such a promising player but has been disgraceful at times for Madrid. Wish him the best of luck though.
