I predict Real Madrid will win or draw in this weekend, and Bale will score a goal. My tuition.
It seems that you are not reading anything at all , it has been stated that there will be few players from real madrid that might not be available from this game especially pepe and ramos so thigs could be tough for them especially when they will be facing atletico that has good records in home game
I think the chance of Real madrid to win at the home of atletico madrid is very small. Moreover, important players of them can not play.
unless real madrid played with full power, they still have a great chance to win at the home of atletico.
We can look at the statistics from their last 5 meetings. real madrid only won 1 time, while atletico madrid win 2 times and the rest was draw
So i think the best choice is atletico madrid win or draw.
