Jagielka is set to face the Brazil star for England this week.
"I don't know a lot about Neymar," Jagielka said. "We don't see a lot of footage. He plays in Brazil so it is tough for us.
"But we have video analysis people when we meet up with England and they will have plenty of footage for us to review.
"They will pick out his good points and bad ones. I am sure the good points will be going on for hours."
