French forward Karim Benzema believes his fellow compatriot Kylian Mbappe is guaranteed to play for Real Madrid in the future.Speaking to the French media after France's 1-1 draw with Bosnia and Herzegovina, Benzema was inevitably asked questions regarding the future of Kylian Mbappe.In response, the Real Madrid forward said he gets along nicely with Mbappe and is keen to partner him at club level soon. Benzema said:“We get along really well, on and off the pitch. Of course that I’d like to have him at Madrid with me even today, but we have to respect his club, he’s there and that’s it. Anyway, he’s a player who will play for Real Madrid one day or another. I’m repeating myself but it’s the best club in the world.”According to Managing Madrid, Karim Benzema has been encouraging Kylian Mbappe to join him at Real Madrid for quite some time now.
