Real meet Barca today in the first-leg of the Super Cup at the Nou Camp.
“Neymar's talent is no secret to anyone, but we know that we cannot be tricked into thinking that Barcelona are going to be weaker because Neymar is no longer with them," said Keylor.
"Whoever plays in his place will have the same drive and ambition."
He added: “Barcelona have great players and a very clear style. There are no secrets to their game. Maybe certain aspects might change with the new coach but their style is very obvious. We know each other well and it will be small details which will decide the game. I hope that we remain focused to make sure we won't make many mistakes."
