The transfer is apparently set to happen whether or not Real salvage their season by winning a third Champions League title in a row.
And Karim Benzema is said to be the man that Real are planning to axe as a direct result of landing Kane.
The French hitman has scored just six goals this term and has supposedly lost the backing of Zinedine Zidane.
