Zinedine Zidane has assured Real Madrid pair Kaka and Karim Benzema they will discover their best form.
The Real legend insists even he struggled to settle at the club during his first six months.
"As always here people are critical. This is the reality. After two months I also went through this difficult time and it will happen to everyone," said Zizou.
"They're both talented players and talented players in Madrid must succeed."
On Sunday's El Clasico, he added: "The truth is that Madrid was very good in this game. They lost, but played a good game. They deserved, perhaps, something more."
