Former Real Madrid player Dejan Petkovic says Luka Jovic will need time to settle.
The striker has arrived this summer from Eintracht Frankfurt.
"I hope Luka succeeds, but he's not going to have it easy," Petkovic told MARCA.
"He's a player that's already shone at Eintracht and I hope he's good enough to wear the white shirt. Lots of great players have worn this shirt, that's for sure.
"He's a striker for the future, with power and speed, who offers different things to Benzema and I hope they're patient with him.
"He will have chances, although he might not have too many at the start. After that, it will all be down to him."
